- acrylic (PMMA)
- acrylonitrile butadiene styrene (ABS)
- nylon polyamide (PA)
- polycarbonate (PC)
- polyethyelene (PE)
- polyoxymethylene (POM)

Which tool steel is right for your plastic injection mold?
Containing 13% chromium, 420 stainless steel is a high-quality tool steel that’s preferred for custom injection molding. The high carbon content provides: Maximum corrosion resistance when fully hardened. Excellent wear resistance and edge retention.
What is 2 shot injection molding?
What is two-shot molding? Two-shot molding, also known as dual-shot, multi-shot, or double-shot molding is a subcategory of injection molding that allows engineers to create multi-material or multi-colored parts without adding extra assembly steps.
What is molding material?
Molding is a manufacturing process that involves shaping a liquid or malleable raw material by using a fixed frame; known as either a mold or a matrix. The mold is generally a hollow cavity receptacle, commonly made of metal, where liquid plastic, metal, ceramic, or glass material is poured.
How many types of injection molding are there?
We can classify injection molds into three types according to the number of parts produced per injection cycle. Read this article to know in detail about the single cavity, multi-cavity, and family mold.
What steel is used for molds?
P-20 is a general purpose mold steel designed for the plastic mold industry. With a combination of Chromium, Manganese, Molybdenum, and Carbon, unwell as being pre-hardened. P-20 is a very popular mold steel grade. P-20 is used for plastic injection and compression molds, and zinc die casting dies.
What is a 2 2 mold?
2 MATERIAL 2 SHOT MOLDING (2K MOLDING) Double Injection in performed on one machine that is programmed to perform two injections in one cycle. In the first cycle, a nozzle injects plastic into a mold. The mold is then automatically rotated and a different type of plastic is injected into the mold from a second nozzle.
What is Double Shot plastic?
Two-shot, also referred to as dual-shot, double-shot, multi-shot and overmolding, is a plastic molding process in which two different plastic resins are molded together in a single machining cycle, as illustrated below.
Why is ABS suitable for injection Moulding?
Benefits: ABS is a tough, impact-resistant plastic that is widely used across many different industries. It has low shrink and high dimensional stability, and it has good resistance to acids and bases. ABS is a good choice for handheld consumer devices. It’s also relatively inexpensive.
Can ABS plastic be injection Moulded?
ABS is a commonly used injection molding plastic, but that doesn’t mean just any manufacturing partner can produce the parts you need. Many injection molders can describe its advantages and applications, but don’t understand ABS’s material properties and processing considerations.
