Actual Case Analysis of Poor Shrinkage (4) Sep 23, 2019
1. Basic information: PMMA Case, shrinkage 2. Description: Using a injection machine with a clamping force of 70 tons (screw diameter of 32 mm, maximum injection amount of 115 g: GP-PS), whether a molded part with a weight of 179.6 g and a thickness of 17 mm can be molded is tested. do. The main problems are as follows: (1) The amount of injection is not enough. In order to solve this problem, we ...

Four major engineering materials in the plastic injection mold industry Oct 12, 2019
ABS, PA, PC, POM are the four major engineering materials recognized by the national standard in the plastic injection mold industry. 1. ABS: It has excellent impact resistance and does not drop rapidly at low temperatures. Even at -40 degrees, it has a very good toughness. The biggest use ABS is as pipelines to transport gasoline, crude oil and water. 2. PA: The biggest feature is low friction co...

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...

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...
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...
