The technology type and difference of two - color injection mould

Two color injection molding mold technology mainly includes core sliding two color injection technology, strip plate rotation two color injection technology, shrinkage model core two color injection technology and core rotation two color injection technology. Below we will do a detailed description and introduction for each two color mold technology.

1. Core sliding two-color injection technology

The core sliding two-color injection technique works by dividing the core into two pieces. For the first injection, slide the core to the specified position for the closing injection, inject the first kind of raw plastic into the mold, and open it once after cooling. The gearing slides the first core out, slides the second core into the chamber, and injects a second plastic. After cooling molding, an injection cycle is completed and then two synthetic products are launched.

2. Strip plate rotary two-color injection technology

The technique should be used to inject the first raw material before work. During injection, the other parts of the mold close the mold, the injection mold is gradually cut off and separated, the rear insert gradually recedes, but it still exists in the plate off part, the mold recedes dynamically, the whole ejector rod and the pull rod part of the injection molding machine cools off, and the first part is completed; The next step of the second part injection operation is generally the same as the first part, but the second injection uses two nozzles to inject at the same time, and waits for curing to push out the two parts together to complete the injection cycle.

3. Shrinkage model core type two-color injection molding technology

Shrinkage mold core two - color injection molding technology mainly adopts hydraulic compression mold. First, under the control of a hydraulic device, a core that can move up and down is pushed into the top ascending position like a piston and injected with plastic material. After the first raw material is cured, the movable core is controlled to fall, and then another plastic raw material is injected, and then the hydraulic device is controlled to press the core upward, to be solidified.

4. Core rotating two-color injection molding technology

This technology is also known as rotary core two - color injection molding technology. The technical principle is to first inject the first kind of raw plastic with the injection equipment, inject it into the hole of the mold, form it into the first kind of plastic, then rotate the mold 180°, use the same injection equipment to inject the second kind of raw plastic until the second kind of plastic is formed, and finally seal the work, complete the basic two-color injection work.

The application scenario of each two-color injection mold technology is different, for example, the core sliding two-color injection technology is more suitable for the needs of large two-color injection parts. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the life is long, the mass production is fast and the finished product quality is excellent!
