If your plastic injection molder suggests a particular gate size or location that you do not feel is optimal it’s important to seek out a second opinion from another plastic injection molding expert. How your part will be used is undoubtedly one of the most important considerations for plastic injection molding design. While this may seem straightforward, there may be some important questions you have missed as part of this identification process, such as:What function(s) will your part serve? Is it a single component or part of an assemblyWhat market(s) is your part intended for?What application(s) will it be used in?Who will be handling your end product?Will the part endure continual use or periodic?Properties If there is insufficient mold temperature the molecules will solidify prior to packing and at different rates, causing mold warpage. The demand for innovative, new plastic products that are lighter, faster, stronger and less expensive than metal ones has gained incredible traction in the last decade. Many Original equipment manufacturers (OEMs) have been moving toward the innovative possibilities that engineered resins offer. Proper material selection is a critical injection molded part design consideration to ensure the finished product survives its intended use, environment and compliance requirements. 

How To Calculate Shrinkage In Injection Molding

In plastic injection molding black specs and splay is usually caused by:Resin Contamination (non-compatible resins, dirt, etc.)Inadequate Resin Dry TimeImproper Melt TemperatureInjection Speed Too HighImproper Gate StyleU.S. Plastic Injection Molder Specializing in Engineering Resins Plastic injection molding is a versatile method used across industries to create a wide array of products, from consumer goods to automotive parts. It involves injecting molten plastic material into a mold cavity, which solidifies to take the desired shape. Unfortunately, many products fail to stand up to their intended use due to selecting the wrong resin material. Tensile strength, impact compression strength, chemical resistance, cooling temperature, and more must be taken into consideration when selecting the right engineered resin for a product’s intended use and requirements. Some plastic engineered resins being used to replace metals include:ABSAcetal Copolymer (POM)Acrylic (PMMA)LDPEPAIPEEKPETPURPPS If your plastic injection molder isn’t compliant with these promises the other 10 promises, it’s time to talk to a legitimate plastic injection molding expert. ABS’ lightweight performance driven properties, paired with its low cost and ease of fabrication has made it an extremely popular resin in plastic injection molding for a wide range of industries applications.

What Is Switch Over Position In Injection Molding

If there is inadequate mold injection pressure or hold time the molecules will not be constrained, which allows them to move around uncontrolled during the cooling process. This causes the part to cool at different rates and results in mold warpage. Unfortunately, burn marks in injection molding are more than just an aesthetic eye sore, they cause degradation within the material and mold properties. This degradation typically results in a compromise of the component’s structural integrity, leading to eventual part failure.

In plastic injection molding, if gate size is inadequate the flow rate of the molten resin will be restricted as it tries to move through. This restriction can cause the filling rate to slow down enough to cause an excessive pressure drop from point-of-gate to last-point-to-fill.
