Most Common Compounds Used For Plastic Electronic Enclosure Manufacturing

Plastics Contract Manufacturers
There are many questions to consider when selecting a plastic for electronic enclosure manufacturing.
Here Are Some Of The Questions You Might Ask Your Company Or Designer:
What is the electrical resistance?
What is the chemical resistance?
Do you have application specific needs, like biocompatibility?
What mechanical properties does it need?

This is just the beginning. There are so many questions to answer, where do you begin? There are many grades, but there are only a handful of plastics that are most commonly […]

OVERVIEW OF PLASTIC INJECTION MOLDING

Plastic injection molding is the method of manufacturing parts made of thermoplastic and thermosetting plastic by melting and forcing into molds where they cool to form the desired object.

Little history about Plastic injection molding
The injection molding process is not a new concept. It came into existence by 1872. By the introduction of plastic injection molding, the plastic industry saw multi-billion dollar earnings, with 32 % of all plastics, by weight processed by injection molding. This has made the plastic […]

Injection mould design

Economical Large Scale Manufacturing
Injection molded parts or finished products are increasingly popular in a variety of industries because the fabricating costs are relatively low after the initial engineering of the die is complete. This method of manufacturing also ensures that each individual part will exactly match every other piece; with the result being finely detailed parts manufactured that can be manufactured quickly in large quantities without losing details. There are many other advantages as well, including strength and durability […]

HOW TO CHOOSE REMARKABLE RAPID PROTOTYPING SERVICES

 
Many companies have turned their attention to rapid prototyping for their needs of creating and developing models and prototypes. Additive manufacturing technology has been a part of the design factors since later in the 1980’s. This process has taken technological advances that have led to the discovery that it can be helpful with creating the actual products rather than just the model or the prototype. Only a few items are created at a time when it is used to create […]

Benefits Of Two Shot Injection Molding

Overview
Imagine cutting your processing time in half. In some cases, that’s possible with two shot injection molding. Two shot injection molding is just what it sounds like – a way to produce two “shots” of something in one step.
The process involves producing two different components, from two different materials, and combining them in one process. This saves time over producing the two different components separately and saves money too since you don’t need to run the entire batch twice. What […]

RUNNER SYSTEM OF INJECTION MOLDS

When molten plastic material leaves the barrel through the nozzle, it is guided toward the mold cavity, its final destination. Its flow path is called runner system, such as the sprue, runners, gates. The runner is in a simple direct route or goes through a series if turns that the flow molten material twists, and restrictions as it approaches the mold cavity. The molten plastic material flows into this cavity, takes the configuration of this chamber in the shape […]

Understanding with the injection molding process

With the use of injection molding presses and high-performance resins, plastic injection molders are able to craft a broad range of quality custom parts. Just as all resins are unique, these sophisticated machines offer varied capabilities and performance options depending on press size and type.
To ensure optimal quality and value, it’s critical to partner with a manufacturer who can provide the right size press for your specific needs.
How Are Plastic Injection Molding Presses Rated?
An experienced plastic injection molder can help you […]

BRIEF HISTORY OF CNC MACHINING

Before CNC machining was invented, all metalworking fabrication processes were completed with NC (Numerical Controlled) machines. The concept of was introduced in 1967 but the first CNC machines were introduced in 1976. Since then the popularity of CNC grew very significant and it was recognized as the industry standard in 1989. Today, we will tell you the brief history of CNC machining.

In 1948, representatives of the US Air Force (USAF) visited the Parsons Corp. headquarters and Parsons was awarded a […]

The main technical key points in the application of hot runner

A successful hot runner mold application project needs many links to guarantee. There are two most important technical factors. One is the control of plastic temperature, the other is the control of plastic flow.

1. Control of plastic temperature
The control of plastic temperature is very important in the application of hot runner mould. Many processing and product quality problems in the production process are directly due to poor temperature control of the hot runner system. For example, the quality of […]

FIVE TIPS FOR RAPID PROTOTYPING PROCESS

Rapid prototyping is a process that uses computer aided tools and techniques such as 3D printing and stereo lithography to create physical product models for production tooling and analysis. The process can be very helpful to product designers, component suppliers and even manufacturers and comes with a number of advantages, such as saving time, reducing cost, lowering error etc. It helps you build and test ideas for product development so that you know whether your idea can be turned into a good product in […]
