Two Shot Molding | Multi-Station Molds: Transfer Molds

For Two Shot Molding, a multi-shot mold is needed. There are several types of multi-shot molding available, such as over-molds, core-back, and multi-station molds. The right mold selection depends on part geometry, volume, quality, and molder capacity/capability.

Silicon Injection Moulding | Multi-Station Molds: Rotational Molds

In 2-Shot injection molding, a polymer is injected over a molded plastic insert to combine the best features of different materials while reducing or eliminating additional assembly operations. This reduction or elimination of post-processing steps is one of the biggest economical advantages of the 2-Shot silicone injection moulding process. For this kind of silicone injection moulding, a multi-shot mold is needed. There are several types of multi-shot silicone injection moulding available, such as over-molds, core-back, and multi-station molds. The right mold selection depends on part geometry, volume, quality, and molder capacity/capability.

Silicone Rubber Parts Weatherproof and Wear Resistant

Semi-crystalline thermoplastic polymers show more order than amorphous thermoplastics. The molecules align in a structured crystalline form. The size of the crystals or spherulites is much larger than the wavelength of visible light, making semi-crystalline materials translucent, rather than transparent. Crystalline regions are small with molecular chains comprised of both crystalline and amorphous regions. The degree of crystallinity in a typical thermoplastic will vary from grade to grade, as for example in polyethylene, where the degree of crystallinity depends on the branching and the cooling rate.

Injection Molding Silicone | Polycarbonate – Amorphous Thermoplastic

Polycarbonate (PC), first introduced in 1958, is an amorphous engineering thermoplastic with exceptionally high impact strength, transparency, high temperature resistance, and dimensional stability. It has a high surface gloss and is available in many colors and color intensities. Additionally, it is impact resistant and maintains high strength and stiffness in a temperature range from -150 to +135˚C.
