Zhongshan, China — (ReleaseWire) — 08/31/2022 — Various industries have already switched from traditional manufacturing processes to plastic injection molding, including but not limited to construction, pharmaceutical, electronics, agriculture, and the automotive industry. There is a long list of benefits as it involves higher productivity, faster manufacturing, operational automation, variable sizes and shapes options, and many other benefits. This proven environment-friendly process allows the creation of complex products through this modern plastic injection molding technique.

There are numerous advantages of mass production, which is a new manufacturing technique and employed under strict supervision and careful operation. Still, some unavoidable defects can be detected during rapid injection molding.

Speaking of those defects and their proposed remedies, one of the most common defects is 'Flow Lines,' which occur when molten plastic flowing into the mold through the tooling cavity gets light-colored lines, patterns, or streaks on the prototype. The best way to avoid getting flow lines is to ensure the cavity is poured evenly with increased injection pressure and speed. In making a steady flow path for the melting material, its temperature should be increased to prevent quick cooling.

Another defect commonly found in injection molding is 'Burn Marks' due to excessive heating resulting in plastic degradation or high-speed injections. The marks usually appear on the outer surface in the form of rusty discoloration. It can be avoided by raising degassing quality or injecting at reduced speeds.

'Warping' is what we call uneven solidification of plastic parts. It can occur on any part of the product, and visible bends and twists can be seen resulting from compression molding. It generally happens from the premature cooling rate, which directly attacks the raw materials that are being used for molding production. Sufficiently delayed cooling can be a good solution to warping, as slow cooling will prevent residual stress from getting entrapped into the product. Other solutions can be selecting unwavering wall thickness or less-shrinkable material.

If you are well aware of plastic injection molding, you must have heard of short shots, which are nothing but missing out on some molding shots. This typically happens when the melting plastic cannot fill the mold cavity completely, and a small portion of the mold is left unfilled. As a result, the final product has an unfilled void, which is useless. To ensure there are no short shots, the best recommendation is to use plastic with low viscosity and melt the mold at increased temperature to ensure proper flow. This way, no gas will be trapped inside, and the mold will be filled evenly.

There can be many other defects in injection molding, which must be identified and rectified on time. Prototool helps you to find better solutions to any of those defects.
