Water-Assisted Injection Molding

Origins and Global Adoption

Water-Assisted Injection Molding (WAIM or WIT) traces its roots back to the early 21st century in Germany and has gradually found its application across the globe. As a counterpart to Gas-Assisted Injection Molding (GIT), the continuous maturation of this technology promises a broader application in the future. Notably, many successful applications can now be observed in automotive door handles.

Basic Principle of Water-Assisted Injection Molding

The fundamental principle of WAIM involves injecting polymer melt into the mold cavity. Water is then introduced into this melt, naturally flowing towards the low-pressure areas of the part where resistance is minimal. As the water flows within the part, it displaces the material, hollowing out thick-walled sections and forming a hollow component. The displaced material is then used to fill the remaining parts of the component. Once the filling process is complete, water continues to exert holding pressure, addressing the volume shrinkage issues during the cooling process. After the mold cools down, the water is expelled, and the part is retrieved.

Comparing WAIM to Gas-Assisted Injection Molding

When juxtaposed with Gas-Assisted Injection Molding, WAIM offers several advantages. Not only can it reduce or eliminate warping and deformation, but it also facilitates the production of products with thinner, more uniform walls and smoother internal surfaces. This helps in avoiding sink marks, conserving material, and reducing internal stresses in the product. Moreover, due to water having a thermal conductivity 40 times that of N2, in addition to the standard cooling mold, water injection also cools the interior of the plastic product. As a result, compared to gas, the cooling time with water can be reduced by up to 70%, allowing products to reach the demolding temperature much faster. Concurrently, water is significantly more cost-effective than N2.

Challenges in WAIM

Despite its advantages, WAIM requires precise control. If the initial amount of injected melt is too little, water might penetrate the melt and enter the mold cavity. The pressure of the water injection must surpass the melt’s pressure to push the melt to the mold’s extremities. Injection molding becomes unfeasible when there are high surface quality requirements.

In automotive interior manufacturing, techniques like WAIM are pushing the boundaries, offering enhanced efficiency, reduced costs, and superior product quality. As manufacturers continue to refine this process, the potential for further innovation remains vast.

Low-Pressure Injection Molding

Understanding Low-Pressure Injection Molding

Low-pressure injection molding is an encapsulation technique that involves injecting thermoplastic material (Check thermoplastic manufacturing) into a mold at an exceptionally low molding pressure, allowing it to solidify rapidly. This method boasts features like insulation, temperature resistance, impact resistance, vibration reduction, moisture prevention, waterproofing, dustproofing, and resistance to chemical corrosion. With its superior sealing properties and excellent physicochemical performance, it offers robust protection to electronic components.

Molding Process and Applications

The process begins by placing the skin material into the mold. Following this, the molten plastic is injected into the enclosed mold cavity through the force exerted by a screw. Once injected, the material solidifies, resulting in the final product. The skin material used in low-pressure injection molding can be fabric or PVC fabric. Currently, this technology has found extensive applications in the production of automotive door panels, pillar panels, and wrap-around rack panels.

Advantages Over Traditional Processes

When compared to traditional wrapping processes, low-pressure injection molding offers several distinct advantages:

1. The skin material and the plastic base material are fused together in low-pressure injection molding, eliminating the possibility of detachment.
2. The absence of the adhesive application process, which is required in traditional wrapping, makes low-pressure injection molding more environmentally friendly.
3. The internal structure of low-pressure dual-layer injection molded parts can be designed freely. Its surface design flexibility surpasses that of wrapping processes, resulting in clearer and more robust design features.
4. The production efficiency of low-pressure injection molding is notably higher.

Given these characteristics, low-pressure injection molding has become a preferred method in automotive interior manufacturing, especially for producing door panels, pillar panels, and wrap-around rack panels. This innovative process not only ensures product durability but also aligns with the industry’s push toward eco-friendly manufacturing solutions.

Conclusion: The Expansive Horizon of Automotive Interior Manufacturing”

The processes discussed above represent just a fraction of the contemporary techniques employed in automotive interior manufacturing. Beyond these, there are numerous other methods, including negative mold lamination, genuine leather wrapping, In-Mold Labeling (IML), and many more. As the automotive industry continues to evolve, so too will the techniques and innovations that drive the production of high-quality, aesthetically pleasing, and functional vehicle interiors.

The paradigm of design, development, and production has been utterly and irrevocably shifted due to the use of advanced manufacturing technologies, tools, processes, and practices. In the field of plastics, important game changers include developments in resin materials, improvements in automation, and networked factories.

These factors will move the industry forward toward a bright future. The plastic products company in the United States has started responding to competition from other countries by embracing new technologies, investing in design for manufacturing (DFM) and other engineering processes that encourage and reward innovation, and so on. The spirit of competition and the development of new solutions will propel the widespread usage of plastics far into the future.

Increased Degrees of Both Automation and Customization

The current trends in automation and customization provide producers with more flexibility in managing and running product assembly. Robots may now be programmed to carry out an extremely wide variety of jobs and are also equipped with vision systems that enable them to do so. As an additional advantage, automation is assisting in developing novel approaches to personalizing produced goods in ways that were not previously possible.

Consumers are growing more accustomed to the ability to customize even the tiniest features of high-end items, such as the aesthetics of the interior and the finishes used on the outside. This is made feasible by sophisticated robots, which have also positively impacted the bottom line of many different manufacturing processes.

5 Innovative Trends We Can Expect to Witness in Plastic Products Manufacturing:

Lowering Production Costs and Improving Material Efficiency:

Plastics are widely used in specialized industries, such as lightweight and energy-efficient car parts, long-lasting and corrosion-resistant construction materials, and numerous medical devices. Following the circular economy idea, the current trend of plastic development to satisfy the needs of specialized sectors is thus targeted at boosting efficiency while reducing resources during manufacturing.

Increased Recyclability:

Plastics are, in essence, completely recyclable materials. It will not pollute the environment if post-consumer garbage is properly managed and processed. To meet consumer demands, the industry has produced plastic packaging by synthesizing and combining plastic with non-plastic materials, resulting in packaging that is not recycled, such as multi-layer film packaging containing aluminum.

 As a result, during K2019, various businesses, including Sabic, Borealis, Dow, and SCG, showed ideas to replace multi-layer packaging, particularly mono-material packaging made of a single recyclable material. Another proposed option is to improve the recyclability of plastics while keeping their qualities.

Waste Conversion into Raw Materials:

Because plastic is a recyclable substance, it is recycled into other raw materials. The following categories of plastic recycling technology exist. Mechanical recycling is converting used plastic into pellets that are molded into new direct-use items. The resulting plastic pellets are post-consumer recycled (PCR) plastic.

They can be blended with new plastic and/or additives to create desired properties for applications such as electronic parts, furniture, and higher-quality packaging for consumer products. For example, LyondellBasell’s plastic gallon jugs are made with 95% recycled PE, Suntory’s green tea bottles are made with 100% recycled PET, and stand-up pouches are made with full PE laminating.

Feedstock and chemical recycling are two more names for how plastic is transformed back into its raw material form. For example, Sabic and BASF have devised a pyrolysis technique for recycling plastic trash that turns non-recyclable or low-value plastic waste that would otherwise be burnt or disposed of in landfills into raw material that can be used for food packaging. Knorr and Magnum bars use this packaging material.

Collaborating with Multiple Industries/Suppliers for Long-Term Success:

Another developing trend that could be witnessed at K2019 is a collaboration between manufacturers and brand owners in creating solutions that address the demands of both businesses and society. BASF and Jaguar Land Rover, for example, collaborated on research into recycling garbage into automotive parts, and SCG and Betagro partnered on the development of robust packaging material for chicken products that are resistant to tears and perforation from chicken bones.

These are just two of countless examples. Furthermore, there were collaborative efforts involving manufacturers, recyclers, brand owners, and other relevant parties across the production chain to develop waste management solutions that optimize utility. This ensures that the plastic sector will develop alongside sustainability efforts, as demonstrated by SCG’s collaboration with Dow to convert post-consumer plastic into recycled plastic pavement.

Manufacturing Bioplastics and Other Materials:

Bioplastics, engineered to enhance biodegradability, can be fabricated from various feedstocks such as corn, tapioca flour, sugar cane, etc. Technological advances like bio-based feedstock and carbon dioxide polymerization have been made to promote the use of renewable feedstock in plastic manufacturing as an alternative to traditional plastic, a byproduct of petroleum, a nonrenewable resource.

 Bioplastics use and post-consumer processing differ from standard recyclable plastics; consumers should verify packaging and sort garbage carefully since bioplastics can contaminate and impair the recycling process.

Conclusion:

With the technological advancements and the economic shifts we are witnessing worldwide, there is certainly extensive potential for improvement, advancement, efficiency, and growth in the plastic products manufacturing industry. So, what trends are you excited to witness first in a plastic production company?

In today’s fast-paced world, where everything revolves around cost-efficient and time-saving production solutions, you may be curious whether low volume manufacturing is also accessible through modern manufacturing technologies or not. But what is low volume manufacturing, and how is it beneficial? 

As the demand for modern innovations and products that we use in the contemporary world is ever-increasing, the need for fast and low volume manufacturing processes is also the need of the hour. Both small-scale and large-scale manufacturing companies and businesses today require low-volume manufacturing processes for certain products, ensuring that the cost and time used in manufacturing are also limited. 

Suppose you’re also someone running a manufacturing business. In that case, you might think, ‘what is the most suitable processing method for low volume manufacturing?’ with the vast array of processing methods used in modern manufacturing businesses and setups, it’s hard to expect the same benefits from every method/process.

As a result, having the know-how of how you can make the product development cycle shorter while keeping up with small-scale manufacturing needs is essential. It not only helps save production time and materials used for manufacturing different kinds of products but also allows you to launch products in the market faster – making a fast profit for the products manufactured per the demand.

So, what ideal processing methods do contemporary low volume manufacturing companies use today? For a detailed insight, let’s go ahead and explore some reliable and effective manufacturing methods below.

How to Choose the Production Processing Method?

As an entrepreneur, whether you’re running a small or large manufacturing business, you may want to know how the product’s manufacturing process is handled in a cost-efficient manner. Usually, businesses opt for high-mix, low-volume manufacturing solutions.

However, when a product production demand is limited or supposed to be managed on-demand, it can be essential for you to go for a production processing method that keeps up with the market demand without putting your business at a loss caused by excessive production. 

How can you do that? It’s simple – you have to know how to choose the production processing method per your product type and demand.

The ideal way to choose a production processing method for any manufacturing business is to evaluate the following production aspects:

Manufacturing Costs:

Whether you are choosing low-volume manufacturing or high-volume manufacturing for a particular product you want to sell in the market, it’s essential to evaluate its cost. The manufacturing cost of a product hugely impacts the production processing method in both high volume and low volume manufacturing processes.

You can ideally choose a method to manufacture the desired product efficiently, depending on your budget. To be more precise, production processes like die casting mold or injection molding can be an expensive option while it is being made and set up. However, once it is made, the batch production managed through it is more cost-effective and time-saving.

In contrast, the CNC milling method doesn’t need any molds and uses a minimal setup. Yet, the production of each piece can be time-taking, thus making it a more expensive production processing method. Considering these factors, it’s essential to evaluate your manufacturing and production processing method budgets to pick an ideal option.

Manufacturing Technique and its Capabilities:

Similar to how the manufacturing cost linked with every production process and setup differs, the manufacturing technique involved in the usage of these setups also differs. However, when it comes to the production process of a specific product, every product and its production is more suitable and offers an ideal final product when it undergoes a technique that gives you the desired end product.

Hence, some production processing methods can only produce items in a particular method/shape. So depending on your production volume needs and the final product you expect to receive, it is a high mix, low volume manufacturing, or either one of them, it’s crucial to choose a process that gives you just that. 

Products Look and Feel:

Yet again, whether it be high volume vs. low volume manufacturing, the quantity of manufacturing isn’t all that should be considered when choosing a processing method that is ideal for your business.

Instead, it is also crucial to opt for a product processing method that focuses on the look and touch/feel of the product, making it just how you have branded or expect to brand to product among the target audience or customers.

Materials Used and Needed to be Produced:

Specific production processes are used for producing only certain materials. So you can’t expect quality, efficiency, money and time saving, and low-volume manufacturing process to be ideal for producing all kinds of products as per your demand.

The quality/volume of production and the type of product that can be produced by a method should go hand in hand when choosing a production process that fits your business’s needs and requirements.

3 Methods for Low-Volume Manufacturing:

Now that you have explored what you should be considering while looking into the low-volume manufacturing process options, it’s time to explore what options you really have. Here are a few product processing methods you can consider reliable low-volume manufacturing strategies:

Injection Molding:

The injection molding production process is ideal for large-scale as well as low volume manufacturing. In this process, plastic or rubber materials are shaped with the help of heated material injected into a mold. 

Different injection molding processes are used in the manufacturing industry today. It includes:

• Cube molding
• Die-cast molding
• Gas-assisted injection molding
• Liquid silicone rubber injection molding
• Metal injection molding
• Micro injection molding
• Reaction injection molding
• Thin-wall injection molding

CNC Milling:

Being a less labor-intensive process, the CNC milling process uses computerized controls to produce a custom-designed product or its part. While the CNC milling process is also suitable for low-volume manufacturing, what makes it a standout is its high quality and precise finishing delivered to every product produced with this method.

In fact, with the CNC or Computer Numerical Control Milling method, a wide range of industries consider it one of the most suitable and quality low volume manufacturing strategies, specifically for its consistency, accuracy, and ability to monitor and increase the uniformity as well as the production volume.

Adding more to that, the computer controls of this production method make it an efficient option that delivers quality production outcomes throughout the milling process. 

3D Printing:

Last but not least, another low volume manufacturing method that many small-scale and large businesses consider for quality outcomes is 3d printing. The 3d printing process is handled through additive processes.

Using this production processing method used in low volume manufacturing companies, you can produce any shape or geometry of objects with the help of digital model data. This digital model data is attained through a 3D model, which is further processed to create a product of the same shape and/or geometry.

Varying between the types of products needed to be manufactured and the production quality demanded, you can use the 3d printing method in both additives as well as rapid prototyping manufacturing processes.

Choosing the Ideal Low Volume Manufacturing Method:

Knowing the type of low volume manufacturing methods is one thing and being well aware of what method may fit your product production process ideally is another. Keeping that in mind, if you’re planning to choose a production method that not only helps in producing ideal products for your business, as per the customer and market demands, but also makes the product fast, efficient, and budget-friendly, it’s vital to pick the production process wisely. 

The best way to make an ideal decision is by considering the following:

• The production creation expense and how much each of the high volume vs. low volume manufacturing process costs
• The development time every process/method takes
• The complexity of the process and the final product they create

Considering these concerns while choosing a suitable product processing method can make it easier to make a decision that helps your business profit in the short and long run.

Picking the Right Production Process Offering Company:

Whether you are a manufacturer or a small business owner, the need for low-volume production for certain or various types of products can be expected. However, arranging costly machinery and managing the entire production can be very hefty to afford when you’re in the initial manufacturing or business stages.
