When we do mold design and manufacture, some big parts requires long ejection stroke, at this time, and the two-stage ejection can reduce the force applied by the ejector pin when it is ejected, thereby avoiding defects in the product.  The two-stage ejection is welcomed by the market and it has the following advantages: 1. Mechanical interlock design, safe and reliable, the ejector unit come...

What is Double Color Mold? Double Injection Mold is also called Two Color Mold. That's two different materials or two color materials injected in one injection machine, injected by twice, but the product only comes out one shot from the mold. This mold technology is called double material injection, usually finished by one set mold, and it needs special two color injection molding machine to produ...

1. The water circiuts of the cavities and cores is designed as full as possible and balanced. 2. After the cavity rotates 180 ° from the center, it must match the core. 3. Usually, injecting the hard rubber part first, and then the soft rubber part, because soft rubber is easy to deform. 4. The nozzle of the three-plate mold should preferably be designed to automatically demolding. Special attenti...

How to process two-color injection moulds? Two-color injection mold, is two kinds of plastic materials in the same two-color injection molding machine, need to be divided into two molding, but the product only mold a plastic mold, usually completed by a set of molds, and the need for a special two-color injection molding machine, that is, we are common on the same plastic products with two colors....

In order to determine the mold damage state and repair measures. Processing enterprises should be in the injection molding machine, under the normal operation of the mold, test the performance of the mold, and the final molded plastic parts size measurement, through these information can determine the existing state of the mold, find out the cavity, core, cooling system and parting surface da...

The process of double color injection molding is a very strict process. If you want to make a good mold, you must strictly control the process of injection molding. In particular, it is necessary to understand the precautions of injection molding of the two-color mold, so as to better avoid some unnecessary problems in the process of injection molding of the two-color mold. So what shoul...
