Injection molding service
Injection molding is a method of producing shapes for industrial products.Products usually use rubber injection molding and plastic injection molding.Injection molding can also be divided into injection molding molding method and die-casting method.Injection molding machine (abbreviated as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make various shapes of plastic products from thermoplastics or thermosets. Injection molding is achieved through injection molding machines and molds.Plastic injection molding is a method of plastic products.The molten plastic is injected into the plastic product mold by pressure,and then cooled and molded to obtain various plastic parts.There are mechanical injection molding machines dedicated to injection molding. The most commonly used plastics are polyethylene,ABS,PA, PC,polystyrene, etc.
As we all know,PC is commonly known as polycarbonate and has very good mechanical properties,so it is commonly known as bulletproof glue. And PC material has the characteristics of high mechanical strength,wide use temperature range,good electrical insulation performance,good dimensional stability,and transparency.Therefore,the use of PC materials can be used in many occasions. For example,it is widely used in electrical products,electrical instrument housings,and electronic product structural parts.On the other hand,there are many modified PC products,usually adding glass fiber,mineral fillers,chemical flame retardants,and other plastics.Another point is that PC materials have poor fluidity and higher processing temperatures,so the processing of modified materials requires a special plasticized injection structure.This is one of the characteristics of the PC.And Regardless of its mechanical properties,or temperature range are very superior.PC also has the characteristics of good insulation and dimensional stability.It can be used in many situations.Of course,the fire performance of PC is also good.
But Whether the design of the injection mold is reasonable will directly affect the quality of plastic products.The main factors affecting plastic shrinkage include thermal shrinkage,phase change shrinkage, orientation shrinkage,compression shrinkage and elastic recovery.
These influencing factors are related to the molding conditions or operating conditions of precision injection molded products.Therefore, mold designers must have rich design and injection molding experience, and must consider the relationship between these influencing factors and injection conditions and their apparent factors,such as injection pressure and cavity pressure and filling speed,injection melt temperature and mold temperature ,Mold structure and gate form and distribution, as well as the influence of factors such as gate cross-sectional area,product wall thickness,reinforcing filler content in plastic materials and orientation of plastic materials.
