Short shot Nov 20, 2019
We are going to talk about one of the most common problem during mould trial--short shot. The factor are as below: 1. It means that the cavity is not completely filled, caused the plastic parts incomplete; 2. The mold venting is not good; 3. The section of gate and runner is too small and long, The melt pressure loses too much during the flow; 4. The thin wall is not thick enough; 5. There is no c...

Venting method for plastic Injection mold Nov 25, 2019
Today we are going to discuss several venting methods for the plastic injection mold: 1. Gate venting; 2. Parting surface venting; 3. Inserts and inserts pin venting; For inserts joint cavities or cores, they can be vented by their split gaps. 4. Ejector pin and ejector sleeve venting; The ejector pin and the sleeve are vented with the matching gap of the core. 5. Porcerax venting; Porcerax is a m...

Guangdong Shenzhen Dongguan Mold Processing Factory Services Nov 29, 2019
The mold in the picture is an extrusion molding mold. It is a mold processed by Russia customer at Green Vitality except for the injection mold. The product is an LED light bar mold shell mold. The full processing cycle is 15 working days, and the next step is to customize the wooden box for export to Russia. In addition to injection molds, Green Vitality also has a lot of mold brother factories i...
The process for injection molding Dec 13, 2019
The Last Shot Stage → Closed mold → Filling → Holding Pressure →Plastic Melting → Part Cooling → Mold Opening → Demolding → The Next Shot Stage During the filling and holding stage, the cavity pressure rises with time. After filling the cavity, the pressure will remain in a relatively static state to supplement the insufficient amount of plastic due to shrinkage. This pressure can prevent the resu...
gas assisted injection mold Dec 13, 2019
Gas Assisted Molding refers to an injection molding technology in which inert high-pressure nitrogen is injected at the appropriate time (75%~99.9%) when the plastic is filled into the mold cavity. The principle of gas assisted injection molding includes: 1.Metrological management 2.Press the high pressure nitrogen gas directly into the mould cavity through gas assisted controller. 3.T...

Uneven color of injection molded parts Dec 13, 2019
The color unevenness is that the color of the product surface is different, and it can appear near and far from the material, and occasionally in the sharp-edged material flow area. Reason: 1. Color unevenness is caused by uneven pigment distribution, especially when color is added by color masterbatch, toner, or liquid colorant. At temperatures below the recommended processing temperature, the ma...
