Plastic injection molded products refer to a variety of plastic products obtained by injecting molten plastic materials into molds through the injection molding process, after cooling and curing.

Plastic injection molded products have the characteristics of lightweight, high molding complexity, high production efficiency, low cost, strong plasticity, corrosion resistance, good insulation and so on. Plastic injection molded products are widely used in various fields, such as home appliances, automobiles, electronics, medical devices, packaging, construction, and so on. But plastic injection molded products in the production process often encounter processing problems, mainly including the following aspects:

Temperature control: The plastic injection molding process requires strict control of the heating and cooling temperatures to ensure that the plastic material can be fully melted and filled into the mold while avoiding overheating which leads to sintering of the plastic or overcooling which leads to unsatisfactory product surface quality.

Pressure control: The injection molding process requires the application of appropriate pressure to ensure that the plastic material can fully fill the mold and avoid defects such as bubbles and voids.

Mold design and manufacture: The design and manufacture of molds directly affect the quality of injection molded products, including factors such as product structure reasonableness, surface finish, and dimensional accuracy.

Plastic material selection: Different kinds of plastic materials have different characteristics, and choosing the right plastic material is crucial to the quality and performance of the product.

Plastic shrinkage: Plastic products will shrink to different degrees after cooling, resulting in dimensional deviation, which needs to be reasonably considered and adjusted during design and processing.

The above are common processing problems in the production of injection molded products, solving these problems requires comprehensive consideration of materials, processes, equipment, and other factors, and requires experienced technicians to carry out effective control and adjustment.

Usually, Plastic injection molded products can use many types of plastic materials, including polypropylene (PP), polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polyethylene terephthalate (PET),  Acrylonitrile butadiene styrene (ABS) and so on.  ABS is one of the most widely used plastics for industrial applications，Since ABS combines toughness, hardness, and rigidity of the three balanced excellent mechanical properties and chemical properties, can produce complex shapes and details, suitable for a variety of injection molding products production.  

However, silicone masterbatch as processing aids/release agents/Lubricants/anti-wear agents/anti-scratch additives can improve the processing properties of ABS materials and the surface quality of finished components. the material obtained by modifying ABS with silicone masterbatch is very suitable for the preparation of various injection parts.

Products that typically use this Modified ABS material include automotive parts, medical devices, electrical assemblies, toys, small appliances, and an assortment of household and consumer goods.

Why does Silicone Masterbatch Optimize Production Efficiency and Surface Quality in ABS Molding?

SILIKE Silicone Masterbatch ( Siloxane Masterbatch ) LYSI series is a pelletized formulation with 20~65% ultra-high molecular weight siloxane polymer dispersed in various resin carriers. It is widely used as an efficient processing additive in its compatible resin system to improve processing properties and modify surface quality.

Compared to conventional lower molecular weight Silicone / Siloxane additives, like Silicone oil, silicone fluids, or other type processing aids, SILIKE Silicone Masterbatch LYSI series are expected to give improved benefits, eg, Less screw slippage, improved mold release, reduce die drool, a lower coefficient of friction, fewer paint and printing problems, and a broader range of performance capabilities.

Adding silicone additives (SILIKE silicone masterbatch LYSI-405) to ABS can do the following:

Increase lubrication performance：SILIKE Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-405 can reduce the friction resistance of ABS material in the injection molding process, improve fluidity, reduce the accumulation of material at the mouth of the mold, reduce the torque, improve the demolding property, and increase the mold filling capacity, make the injection molding smoother and reduce the possible defects such as thermal cracks and bubbles.

Improve surface quality: SILIKE Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-405 can improve the surface performance of products, enhance the smoothness of the surface, and reduce the coefficient of friction, so as to improve the finish and appearance quality of products.

Increase abrasion resistance: SILIKE Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-405  has good abrasion resistance, which can give ABS products long-lasting abrasion resistance and scratch resistance, and reduce the wear and damage caused by friction during the use of the products.

Increase production capacity: SILIKE Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-405 has better stability than traditional processing aids, can effectively improve product processing performance, reduce product defective rate, extend the service life of the product, increase production capacity, and reduce the overall cost of production.

In conclusion, the addition of silicone additives (SILIKE silicone/Siloxane masterbatch 405) can improve the processing performance of ABS materials, improve the surface quality and durability of products, and increase the added value of products.

However, in actual application, the specific type and dosage of silicone masterbatch need to be reasonably selected and adjusted according to different plastic materials and product requirements, If you encounter any issues regarding the Processing Performance and Surface Quality of Plastic Injection Molded Products, SILIKE is delighted to offer solutions.
