Plastic injection molding is typically reserved for high-volume part production. If this manufacturing process is appropriate for products you're trying to create and sell to an audience, here are some key suggestions to remember.
Be Gradual When Transitioning to Different Wall Thicknesses
An important design aspect to remain cognizant of with plastic injection molding is wall thickness. You may have areas where this attribute varies and if that's really necessary, you just need to be gradual going from one wall thickness to another.
What this does is let the resins inside your mold properly move into cavities, for a refined molded part at the end. Also keep in mind that the fewer variances there are with wall thickness, the easier it's going to be making quality parts using this fabrication method. You won't have lingering defects that add to manufacturing time and costs.
Used Ribbed Sections for Reinforcement
If you're trying to reinforce your parts, you don't necessarily have to make the walls too thick when going forward with plastic injection molding. A better approach might be to use ribbed sections. These ribs are basically portions that protrude outward.
They're fairly easy to incorporate into injection molds and will give your part more structural stability. Only, you won't have to use a lot more materials and complicate the molding process. You just need to make sure these ribs are placed at the right locations so that strength is improved in a meaningful way.
Review Part's End Use
You can use a lot of different resins in plastic injection molding today, but there's probably one, in particular, that's going to serve your part operations best. You need to review your part's specific end-use to properly select a resin that has the right properties and takes well to plastic injection molding.
For instance, if your parts will be exposed to hot environments, you'll want to choose resins with heat-resistant properties. Or maybe your parts will be around chemicals, which will require chemical-resistant resins. This type of thinking will help you make a compatible resin solution in no time.
If you're making a part through plastic injection molding, you want to carefully review this manufacturing process and see how you can get the most out of it. Then plastic injection molding won't be able to go off the rails and cause you a bunch of headaches when trying to create a certain part.
