From the customer's perspective, the most feared thing for customers is to receive defective shells produced by Plastic Mold manufacturers. For example, the shells are easily too brittle and easily broken. If it is found to be okay before assembly, and if it is shipped to the customer after assembly From the customer's perspective, the most feared thing for customers is to receive a defective shell produced by a plastic Mold manufacturer. For example, the shell is prone to being too brittle and easily broken. If it is found to be okay before assembly, but it is not until the product is shipped to the customer after assembly that it is prone to being brittle and broken, leading to a return, the problem becomes serious. What is the reason why the shell products produced by plastic molds are too brittle? The shell products produced by rubber molds are too brittle, mainly due to the following reasons: 1. The shell products produced by plastic molds have too many water inlet materials infiltrated into the raw materials, even more than the raw materials, especially black ones. If too much is added, it becomes particularly brittle and can break with just a gentle break by hand. 2. When producing shell products, plastic mold manufacturers may have a high temperature in the barrel, which may scorch the raw materials and cause the product to be brittle. Therefore, plastic mold manufacturers must control the temperature well during the production process. 
3. When selecting materials for products, it is more careful, such as PS raw materials. Although the transparency is relatively high, it has a disadvantage that the product is prone to brittleness. It is recommended that plastic mold manufacturers choose materials reasonably according to the product requirements.
