Do Plastic Injection Molds Need to Have Shrinkage?

Welcome to JS Precision Company’s latest article! We are a professional injection mold manufacturer that takes pride in delivering high-quality products with precision and speed. In this article, we will be discussing the importance of shrinkage in plastic injection molds.

Firstly, let’s define what shrinkage is. Shrinkage is the reduction in size or volume of a material as it cools from its molten state to its solid state. In the world of plastic injection molding, shrinkage is a natural occurrence that happens during the cooling process. This means that the part that is molded will be slightly smaller than the original mold due to the material contracting as it cools.

So, do plastic injection molds need to have shrinkage? The answer is yes! Shrinkage is an essential factor that must be taken into consideration when designing molds. Without shrinkage, the finished product would not fit precisely into the intended space or structure. This would result in poor-quality products that would not be suitable for their intended use.

Moreover, it is important to note that different types of plastics have varying degrees of shrinkage. For instance, thermoplastics have high shrinkage rates, while thermosetting plastics have low shrinkage rates. This means that the mold design must be adjusted accordingly to accommodate the type of plastic being used.

At JS Precision Company, we understand the importance of shrinkage in plastic injection molds. Our team of experts has years of experience in designing molds that take into account the shrinkage rate of different types of plastics. We use the latest technology and equipment to ensure that our molds are of the highest quality and precision.

In addition to designing molds with shrinkage in mind, we also conduct thorough testing and analysis to ensure that the finished product meets our client’s specifications. This means that our clients can trust us to deliver products that are of the highest quality and precision, regardless of the type of plastic being used.

So, the next time you need a plastic injection mold, remember to choose a manufacturer that understands the importance of shrinkage. At JS Precision Company, we take pride in delivering products that meet our client’s specifications, and we do this by designing molds that take into account the shrinkage rate of different types of plastics.
