What does an injection molding machine do?

The molding machine heats the plastic until it is liquid. The nozzle of the injection molding machine then injects the melted plastic into the mold (injection pressure). The cavity of the mold is now filled with the plastic liquid. This will then cool down to form a solid product.

What is an injection molding machine called?

Injection moulding machines consist of a material hopper, an injection ram or screw-type plunger, and a heating unit. Also known as platens, they hold the moulds in which the components are shaped. Presses are rated by tonnage, which expresses the amount of clamping force that the machine can exert.

What is a 2k machine?

2k injection molding is a manufacturing process used when referring to molding two materials/colors into one plastic part. This plastic molding technology blends two materials or two different colours materials into one ending plastic part by using 2k injection molding machine.

What is 3 plate mold?

A three-plate mold is used when part of the runner system is on a different plane to the injection location. This second parting plane enables the runners and sprue to be ejected when the mold is opened. In the following diagram of a three-plate mold, the runners will be ejected separately to the cavities.

What is double injection 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 1K Moulding?

1K injection molding By injection molding a wide range of plastic parts with a weight of 0.5 to 8,000 g is produced. The entire range is processed from standard to highperformance plastics, with a total of more than 1ooo t of granules per year.

What is 2 plate mold?

Two plate mold is the easiest injection mold structure and has many advantages. It’s consist with A side and B side 2 main parts, when it is load in ejection machine to do molding, A side is fixed and held still, B side is movable.

What is a platen for injection molding machine?

US20040131724A1 – Platen for an injection molding machine, and two-platen injection molding machine equipped with such a platen – Google Patents A platen of an injection molding machine includes a plate-shaped center area having corners, each corner formed with a recess.

Why are locators important on a rotary Platen mold?

With a rotary-platen mold, it is critical to have locators on the mold and the machine platens to ensure that it is exactly on center of the rotary platen. If the mold is not exactly on center, you will have alignment issues; when the mold rotates 180° it can damage the leader pins, bushings, and shutoffs.

How does two-shot injection molding work?

This four-cavity mold is mounted on a rotary platen that enables a 180° rotation of the core side of the mold. This rotation moves the first-shot cores into alignment with a second set of cavity steel for the second shot. (Photo: MGS Mfg.) Those not familiar with two-shot injection molding may assume that it’s complex.

How do you mold ejector plates in one cycle?

So in one cycle you are molding the first shot with the base material and molding the second-shot material over the first-shot parts from the previous cycle. There are two sets of ejector plates because you are only ejecting the parts with both materials molded, leaving the others to have the second shot molded.
