Custom Injection Molders

Evaluating A Custom Injection Molder
Ever since its inception, injection molding has become a popular technique to form a variety of different products. Its strengths lie in its ability to recreate objects en masse, producing thousands of replicas based upon a single template. Driven by automation and requiring minimal human guidance or interference to run properly, the technology remains a top choice for any company that seeks massive reproductions.
But how do you know that you’ve found good custom injection molders? […]

Injection Mold Manufacturing

Injection Mold Manufacturing and Plastics Production
As early as the 1860s, people were learning how to make and use plastics. Due to its flexibility when warm and ability to hold a shape when cool, plastic made it easier to create new products. Unfortunately, it was difficult to produce affordable, quality plastics that did not warp or break.
As manufacturers experimented with plastic polymers, small items became easier to produce in greater quantities. But it wasn’t until the 1940s, when demand for large amounts […]

Injection or thermoforming: what’s best choice for custom plastic molding

Custom Plastic Injection Molding
Custom Plastic molding offers a versatile and wide range of applications, from food storage to medical supplies, and beyond. However, the manufacturing of each part or tool is just as unique as the part itself. Two of the most prominent manufacturing methods are injection molding and thermoforming. Here, we’ll highlight how each works, as well as the advantages and best use of each.
As we mentioned, thermoforming and  injection molding are the most widely used manufacturing processes. Both offer […]

8 DESIGN RULES FOR PLASTIC INJECTION MOLDING PROCESS

When designing for manufacture with plastic injection molding, there are still more guidelines to be taken into consideration. The easier it is for the toolmakers to create your mold, the faster your turnaround time will be, increasing the speed that your product will be out there for consumers. Here’s 8 design rules to follow when designing for manufacture:
1. Coherence. Try to make your design uniform throughout. That is, wall thickness, rib thickness and corner radii, for instance, should all be […]

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 […]

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 […]

Hot runner of injection mould

In order to simplify the injection molding process and reduce the waste of parts, it is important to eliminate the need for a large auxiliary cold runner. The key is to ensure that the melt remains molten throughout the flow channel system so that it does not solidify until it reaches the cavity wall where the cavity is cooled.

Internal heating hot runner:
The internal heating hot runner system is the first hot runner system to be put into the market. […]

Cold Runner of injection

The advantage of cold runner is that it is easy to use and can meet some aesthetic requirements. The cold runner reduces injection into transparent acrylic or polycarbonate parts used for light transmission, avoiding the visible banding effect of injection in some parts.

In addition to the waste of raw materials, the defects of the cold runner include adding steps to the whole automation or manual process. Removing the cold runner from the parts of the mold requires robots or […]

HISTORY OF PLASTIC INJECTION MOLDING

Plastic injection molding originated with chemists in Europe and The United States who were experimenting with plastics. Originally it was done by hand and pressed into a mold using Parkesine but it proved to be too brittle and flammable. John Wesley Hyatt is the official inventor of plastic injection molding and the process has a rich history with brilliant minds.
John Wesley Hyatt was a creative inventor and developed the processing of celluloid plastics. This was an amazing feat for […]
