PLASTIC INJECTION MOLDING – CONSULTATION

Advice on practical part design concepts! Contact Us for advice on how best to get your plastic part manufactured. During your personalized consultation, we will go through the following with you.

• Material selection: What’s the best material to use for your plastic part? The two we use are Commodity resins and engineering resins.

• Part-forming: What’s the best way to get your part formed correctly to ensure as few defective parts as possible. The most common part forming processes we use are:
  1. Warping – Plastic parts that are not designed correctly will warp.  An easy example of a plastic part that will warp is any “L” shape or “T” space with the same material thickness, will warp.  There are ways to correct the plastic part design.
  2. Ribs – Adding ribs instead of thickening up a plastic part will not only make it stronger but also less expensive if done correctly.
  3. Strengths – Plastic material types have different characteristics.  Different material types are good for different applications.  A rigid or tough material may have the strength but visually unpleasing.  A visual material may be weak and not hold up to the application. There are also additives that increase strength including glass, carbon and others.
  4. Tool steels – It is important to choose the correct steel for the injection mold tooling.  Many aspects go into deciding what steel (or aluminum) is recommended. Plastic injection molding materials can be abrasive and/or corrosive which if prematurely wear the plastic injection molding tool.  Yearly part volumes will also determine what type of steel or aluminum to use. Common tool steels include P20, S7, H13. Aluminum can also be called out for low volume production runs and prototyping.

• Tolerance for your plastic part is directly related to its overall size and measurements. The Measurements determined will provide you a clear idea of what to expect.
