Injection molding defects can often result from the material itself or how the manufacturer stores and processes the material prior to the production process. These defects range from minor aesthetic problems to reduced strength of finished components. Depending on the intended use of the affected product, serious safety concerns can also arise. Discoloration Discoloration or "color stripe" occurs when the color of the molded part is different from the expected color. Usually, discoloration [...]

In the process of injection molding problems will also affect the quality of the product itself. The following defects usually occur: Warping Warping refers to the deformation that may occur in the injection product when different parts of the component contract unevenly, and uneven shrinkage will exert excessive stress on different areas of the molded part. This improper stress can cause the finished part to bend or twist as it cools. Causes and [...]

Making injection molded prototypes is both an art and a science. A high level of technical expertise and attention to detail is required to prevent small mistakes that cost the company a lot of money when producing novel parts in small batches. Some molding defects may be difficult or costly to fix. By adjusting the molding process, other situations can be avoided without the need to redesign the mold or replace other production [...]

Injection molding is of great importance to our industry. Its main advantages are fast production speed, high efficiency, and automation, a wide variety of designs and colors, simple to various shapes, large to small sizes, and easy upgrade of sizes and products. Injection molding is suitable for the mass production of products with complex shapes and processing fields. Several important parameters affecting injection molding production are listed below: Injection pressure The injection pressure [...]

After the mold is set, some processing of the purchased materials is required before injection molding, mainly drying and dehumidifying (water absorption). The key process in injection molding is to dry the plastic before injection. The reason plastics have to be dry is that they contain water, which, if not dried, can affect the quality of the finished product. Polymers such as polycarbonate, PC, PBT, PET, ABS, acrylic, polyurethane must be thoroughly dried. [...]

After completing the construction of the new injection mold, you also need to set up the injection mold for testing or molding the plastic. Here are some things to note when setting up an injection mold: Opening and trying all movements In this step, we will perform die closing and die opening tests on the mold. In the mold closing test, we mainly measure whether the die is closed during the die closing [...]
