Post Processing of Plastic Injection Products

Plastic parts can not be directly put into use after molding and demoulding, and some treatment is needed. Because this treatment is carried out after molding and demoulding, it is called post-processing. It is described as follows:

Trimming

After demoulding, the plastic parts always have some excess materials, such as gate flying edge, which bring disadvantage to the appearance and use of the plastic parts, so it needs to be removed. This kind of removal is relatively simple, and can be […]

How to Control The Chromatic Aberration of Injection Molded Products

Chromatic aberration is a common defect in injection molding. It is not uncommon that the color difference of the matching parts causes the rejection of the injection molding machine in batches. There are many factors affecting chromatic aberration, including resin, masterbatch, masterbatch mixing with raw materials, injection molding process, injection molding machine, mold and so on. Because of the wide range involved, chromatic aberration control technology is also recognized as one of the more difficult technologies to master in […]

Differences Between Double Color Mold and Overmold

Double color mold: two kinds of plastic materials are molded on the same injection molding machine, and are molded in two times, but the products only die once. Generally, this molding process is also called double injection molding, usually by a set of molds, and a special two-color injection molding machine is needed.
Overmold: two kinds of plastic materials do not have to be injected into the same injection machine and are molded in two times. After taking out the […]

Are You Getting All You Can From Your Manufacturing Engineering Services Partner

Plastics In-House Engineering Capabilities
Most manufacturers get components and assemblies from a variety of vendors. It’s not cost-effective to produce these items in-house. However, your vendors don’t have to be just glorified warehouses that provide pieces of your products. A full-featured manufacturing engineering services partner offers not just manufacturing but also engineering design and support.
Manufacturing and Engineering Services
Obviously your first concern with manufacturing engineering services is their ability to manufacture. You need to be sure the company has the capacity […]

Benefits of using hot runner for plastic injection molding

Hot runner system for plastic injection molding saves plastic, shortens molding cycle, reduces production cost and improves efficiency. Hot runner mold is widely used in all developed countries and regions in the world. This is mainly because the hot runner mold has the following notable characteristics:

1, shorten the forming cycle and improve the production efficiency; because there is no restriction of the mainstream and secondary cooling time, the parts can be ejection in time when molding is solidified. Many thin-walled […]
