Injection Molding is a manufacturing process for producing parts from both thermoplastic and thermo-setting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the mold cavity.
Some advantages of injection molding are high production rates, repeatable high tolerances, the ability to use a wide range of materials, low labor cost, minimal scrap losses, and little need to finish parts after molding.
Some disadvantages of this process are expensive equipment investment, potentially high running costs, and the need to design moldable parts.
A very wide variety of products can be made by the injection molding process, ranging from automotive bumpers to mugs and buckets.
Because of this, injection moulders also face a wide variety of problems. On one hand, the processors moulding very large / intricate pieces need to improve flow of the product, using products like ProcezAid, on the other hand, the processors using recycled polymers have a need for increasing shine in the finished product and use Shinex to improve shine.
A typical problem faced by injection moulders is during colour change or during material change. Streaks of the earlier used colour can keep appearing in the new colour, thus causing contamination and loss of productivity and profits. The solution is using Purging Agents.
