Injection Molding Surface Finishing
Injection molding surface finish is critical to a successful part design and it is used for aesthetic and functional reasons in injection molded parts for engineering products. The surface finish improves the look and the feel of a product as the perceived value and quality of the product increase with a suitable surface finish.
Glossy
A-grade finish is smooth and highly reflective, giving the product a shiny appearance. It’s often used for products where aesthetics are important.
Semi-glossy
The B-grade finish is less reflective than glossy but still has a smooth and somewhat shiny appearance.
Matte
C-grade finish is non-reflective and has a dull appearance. It’s often chosen for parts where glare or light reflection is undesirable.
Textured
D-grade finishes are intentionally rough or patterned. They can provide a better grip or a unique appearance to the product.
The Plastic Injection Molding Process
Plastic injection molding is the process of filling a mould or mold tool with molten plastic under setting pressure. The tool may comprise a single cavity, multiple cavities, or family cavities in order to make indefinite numbers of parts. Assuming that the mold has been prepared. The injection molding process consists of the following basic steps:
1. Clamping
The first step of the injection molding process is clamping. Injection molds are typically made in two pieces. In the clamping phase, the two metal plates of the mold are pushed up against each other in a machine press.
2. Injection
When the two plates of the mold were clamped together, the molten plastic was injected into the mold.
3. Cooling
Put the mold alone, cool and solidify the plastic into the end-use product that can be safely removed from the mold.
4. Ejection
Open the mold, an ejector bar slowly pushes the solidified product out of the open mold cavity.
