When trying to develop products or new products, don't just focus on product design, neglect plastic mold manufacturing.  Some users tend to focus only on product development and development, ignoring communication with plastic mold manufacturers. After initial determination of the product design plan, there are two advantages of contacting the mold manufacturer ahead of time. 1. You can ensu...

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...

Today, we are going to talk about the plastic injection machine system, The daily products are basically molded by plastic injection machine,  Some of them are produced by full automatic, some are by  half manual,  It depends on the customer's request or the product feature. The injection molding machine system include seven systems, as below: 1. Plastic injection system, 2. Opening...

Plastic raw materials have many different types.Today we will take about the engineering plastic materials.So what are the Four Major Engineering Materials and what's their applications ? The answer is as follow: 1.ABS, full name is Acrylonitrile Butadiene StyreneAcrylonitrile Butadiene Styrene. It's widely used in machinery, automotive, electronic appliances, instrumentation, textile and construc...

Product warpage the reason: 1. The product design is unreasonable. 2. The product is too thick. 3. Uneven cooling. 4. Injection pressure is too high. 5. Incoming water design is unreasonable; different flow directions shrink differently. 6. Too many undercuts. 7. The thimble is not enough. 8. The mold cavity is too hot. 9. Reversal of material filling. 10. Unreasonable material selection. Solution...

1. Gate: generally, 3-point or 6-point is used for balance. For micro gears, usually single point is used. 2. Mold cavity: usually for 1~4 cavities. Small gear can reach 6 or 8 cavities; Different shapes of gears could be 3 cavities. The most representative is 4 cavities. 3. Ejection: normally use center ejector sleeve and ejector pin. For the helical gear, a bearing must be added to assist the ej...
