Plastic molding technologyPlastic molding technology continues evolving with the market and with the advances in science. Plastic molding is the process used in producing plastic components for a variety of industries.

When plastic resin materials are heated the resin will flow, and can then be injected into a mold. A plastic mold consists of two halves referred to as the “A” side and the “B” side. The “A” side is where the molten plastic enters the mold – and the “B” side contains the ejector system which removes the parts.

There are normally two ways to do plastic mold polishing:

1. Do it in-house.

When we do the mold polishing in-house we could keep the time control.  And will be easy to communicate with your polishing department to keep the high-quality polishing job, this will prevent the issue happened by the over-polishing jobs.

2. Do it outsource.

  • You still can take control of the lead time easier by scheduling the polishing to an outside polishing company. Especially for some multiple cavities molds, because they have many polishing workers and can work on polishing cavities separately.
  • But when meet some issue that will be difficult to discuss with each other, if your polishing supplier is close to you, […]

A mold used to form a product using the injection molding process. A standard injection mold is made of a stationary or injection side containing one or more cavities and a moving or ejection side.

The resin, or raw material for injection moulding, is usually in pellet form and is melted by heat and shearing forces shortly before being injected into the mould. The channels through which the plastic flows toward the chamber will also solidify, forming an attached frame. This frame is composed of the sprue, which is the main channel from the reservoir of molten resin, parallel with the direction of draw, and runners, which are perpendicular to the direction of draw, and are used to convey molten […]

Co-injection molding(or sandwich molding) a process that creates a skin and core material arrangement in a molded part. The skin material is injected first into the mold cavity, and is immediately followed by a core material. As the skin material flows into the cavity, the material next to the cavity walls freezes and material flows down a center channel. When the core material enters it displaces the skin material in the center of the channel by pushing the skin ahead. As it flows ahead it continues to freeze on the walls producing the skin layer

Machine Based Co-Injection molding

The Co-Injection process requires two injection/processing units. The units generally inject material through a manifold located at the end […]
