Top Injection Moulding Companies
Custom plastic moulding is a process used in a broad spectrum of industries. The advantages are clear, so long as the company you choose to do your work manages to avoid quality shortcomings that result from material and processing issues. As you assess their engineering and production staff, their facilities, and the toolroom, remember that top quality is your main concern. Choose a custom plastic moulding company where quality is king.
Why Choose Custom Plastic Moulding?
Injection moulding is the process of choice when you want a high-volume of parts that require little post production work due to the finished appearance of the parts after injection. To produce complex parts, you can use inserts in the mold as well as filters for strength, and even employ multiple materials. The process can be completely automated and scrap reused to create parts that are cost effective and green.
Custom plastic moulding uses a vast array of polymers or resins to create the parts. Over the past 20 years, nearly 750 new materials per year were added to the base of 18,000 that were known in 1995. Advances in polymer science have improved the properties of various thermosetting plastics such as epoxy or phenolic, and thermoplastic such as nylon, polyethylene, and polystyrene. If you want to experiment with the properties of different materials, the sky’s the limit in what you can choose as you aim for the perfect part.
Potential Problems In The Process
As with any process, the results from custom plastic moulding may not be what you would expect. Your anticipated fine finish can be marked by blistering, burn marks, uneven colour, flow marks, deformities, and a host of other problems. Most defects result from equipment, material, or processing errors.
For example, here are a few common errors and their causes:
