Plastic Injection FAQ
What is injection molding?
Injection molding is an extremely versatile and popular form of molding. Other processes include extrusion, thermoforming, compression, and blow molding.
In injection molding, plastic granules are heated and injected under pressure into metal molds, where the molten plastic hardens into the designated shape. The mold then opens and the formed part is removed and inspected. The part is then ready for shipment or for secondary manufacturing operations, such as screening or perfing.
Do you provide quotes over the phone?
We do our best to capture the information needed to provide an accurate quote. Please provide the following information, if known:
- Part weight
- Type of plastic
- Total shot size
- Overall part/mold dimensions
- Mold open dimensions
For a more accurate quote, we encourage customers to submit a request through our online form system.
Do you provide short/long production runs?
We specialize in small or large production runs ranging from as little as 10 parts at a time up to 1,000,000 or more.
How long does it take to build a mold?
The average mold takes approximately 10 weeks to build. We have built molds in just a few weeks, but some molds can take 5 months or longer depending on part complexity and the number of cavities.
How long after mold completion until I receive my parts?
After the initial mold sampling, the parts are measured and sent to the customer for evaluation. Once parts are approved by the customer, there is typically a one or two week lead-time for production parts.
What types of materials can be molded by Modor technical Products?

I have a concept for a molded product. How do I get started?
First we will meet with you to go over your project in detail, reviewing your product concepts and quantity needs in order to select the right materials. We then provide you with a price quote for the mold and for the injection molded parts.
After your order is placed, we will create a CAD drawing and print it out for a visual approval, then follow up with a mold and sample parts. In most cases, we deliver a prototype mold prior to final approval. Please visit our process page for more information.
Why is it important to develop a product prototype?
A prototype is a quick way to find out if you are on the right track with your plan or design. It is often the best way to gather feedback from users while you are still refining your design.
Prototypes are cost-effective to modify early in the development process. In addition, having a prototype of your product can help build creditability with potential investors.
