If you have an idea for a custom plastic part, you may have a lot of questions about the manufacturing process. Injection molding is a time-efficient and cost-efficient way to achieve the quality part you need.
Here are answers to some of the most frequently asked questions about custom injection molding:
How do you know if injection molding is the right process for a product?
There are several ways to manufacture a plastic part. Understanding and knowing the part design, the end function of the part, the quantity needed, and the target part cost will help determine if injection molding is right for you.
What is the minimum number of units required for a new molding project?
Due to the high cost of the mold ($10,000 – $200,000), injection molding is typically a good choice if you need a higher volume/quantity of your part. If you only need 100 parts, injection molding may not be right for you. This depends on your budget and how critical the part design is to your project’s success.
Will a prototype be tested for durability and usability before the mold and lot are produced?
Sometimes yes, only if the customer requests it and or if it’s recommended by our engineering team. There are two types of prototypes: prototype parts made by a 3D printer (extremely small volume) and prototype molds (which will produce exactly what the production mold will produce). The prototype mold is used to produce many parts for sizing and extensive physical testing, prior to production mold build.
How do you know what type of resin is best for a product?
Since there are over 100 different types of resins, we’ll need a good understanding of your vision for the product and what it will be used for. If it needs to have physical requirements like a special color or specific heat resistance, among many other possible factors will help determine which type of resin will meet those needs.

How long does it take to build a new mold?
Depending on the complexity of the part, the number of cavities (parts in the mold), and the size of the mold, it can take anywhere from 2 to 26 weeks to build a new mold.
Will the molds for my part be maintained between production runs?
Yes, all molds at Pioneer Plastics are on a PM (preventive maintenance) schedule.
Can the injection mold be modified after the first run of production?
In some instances it can, but not always. It depends on what the change is and whether or not it interferes with the function of the mold. If the modification is major, it may simply require a new mold.
Are there any size limits on parts that Pioneer Plastics can produce?
Pioneer Plastics can produce items as small as a pen cap and as large as a lawn chair. Learn more about our injection molding machines here.
Does Pioneer Plastics offer secondary services (like part assembly)?
We offer assembly, in-mold decorating, pad printing, heat transfer decal, and more. Learn about all of the additional services we offer here.
