Understanding Injection Moulding Technology

Injection moulding can achieve nearly everything. This technology, invented in the 1940s and constantly upgrading, allows for unimaginable flexibility in product design and has revolutionized mass production. It's a popular manufacturing process where parts are made through the injection of molten materials into moulds or dies.

Careful choice of cheap injection moulding services ensures you get value for your money. You need to have adequate information about a good moulding company at your fingertips if you're to make an informed choice.

Wide Application

Injection moulding is used for almost all plastic products that you come across on a daily basis. Everything from the cap of your favourite lotion to the dashboard of your luxury sedan has been created through the injection moulding process. Even the plastic components that make up the smart phone or laptop computer that you're using right now have been injection moulded.

There are many materials that are compatible with injection moulding, almost anything that can be malleable - from plastics to metals. The machines involved vary in size, appearance and running costs, allowing for increased customization.

As with most items manufactured in large quantities, they can be made from the same mould time and time again, meaning the cost of designing the mould is spread over the total number of items manufactured. This is the reason why products like toys and DVD cases are cheaper than limited-run products like vinyl toys and customized art pieces.

Finding a cheap Injection Moulding service.

A good injection moulding company is one that should take measures to ensure there are no moulding defects, and if such defects exist, it should be its responsibility to rectify them, including creating new parts. Some of the most common defects include embedded contaminants, warping/twisting, polymer degradation, de-lamination, blistering, colour streaks, flow/sink/splay/burn marks, short shot, weld/knit lines, voids and stringiness.

The company should be able to offer cheap injection moulding services without sacrificing aesthetic appearance. Such a company will have the capacity including skilled manpower, tools and equipment to do the job.

It should provide complete and affordable services, meaning it should do everything from designing, optimization, tooling, the actual injection moulding, assembly, additional printing and testing. In-house testing is quite important because it ensures that the parts delivered will work.

Quality Control

An injection moulding company which makes quality and cheap parts is one whose quality control system meets ISO 13485 and ISO 9001 requirements. The company should use sophisticated manufacturing technologies and there should be automation such as the use of robots. Automation is necessary because it reduces human error (and consequently greater levels of quality) and reduced operational costs.

A reliable injection moulding company is one that has been in the business for many years. This is indicative of its reliability and credibility. It should have a credible history of meeting strict deadlines. The company should have appropriate licenses and it should use eco-friendly manufacturing methods.
