Mold injection materials
Mold injection parts are often compared to injection molded materials. For example, a rigid molded injection molded part might be described as "polycarbonate-like," while a more flexible plastic might be described as "polypropylene-like." We have divided our molded materials into general categories to help you make decisions faster and get the best performance in your project. The list below describes material categories and technical examples when selecting polyurethane.

Available Finishes for Mold injection Parts

Parts have a smooth, satin-like finish due to the master pattern being bead-blasted matte. Clear and translucent parts with this finish will appear frosted. Matte finishes are useful for handheld and high-touch areas as it reduces fingerprint visibility.

A finish that includes some sheen but not high reflectivity. Semi-gloss finishes are in between high-gloss and matte, resulting in a smooth, easy-to-clean surface.

A highly reflective finish is made by polishing the master pattern before making the mold. High-gloss has a high sheen and will have the highest transparency for clear parts. High-gloss is useful for cosmetic models, cleanable surfaces, and lenses.

Zhuofei can provide additional processing, including custom textures, secondary finishes, painting, and more.

Mold injection Options

Polyurethanes can be blended with pigments to achieve a variety of colors. Naturally, a urethane may be amber to milky-white in color. Zhuofei’s clear urethane options are formulated to be colorless. Below are Zhuofei’s color options:

  • Black
  • Color-Match
  • Natural (unpigmented)
  • Clear (colorless)

Overview: What is mold injection molding?

Injection Molding is a production process commonly used to manufacture plastic parts. This process forms various complex shapes of parts by injecting molten plastic into precision-made molds. The following are the basic processes and main features of mold injection molding: It can produce parts with high precision and complex geometric shapes. The mold design and manufacturing accuracy determine the quality of the final product; it is suitable for mass production, with a short production cycle, and can produce a large number of parts in a short time; various thermoplastics and thermosetting plastics can be used to meet different application requirements.
