Procision Manufacturing
The Plastic Injection Molding
Plastic injection molding is a process where liquid plastic resin is injected into a mold under high pressure where it cools and solidifies to form a finished part. Depending on the tool design, molds can produce single or multiple parts in each cycle, enabling efficient large-scale production.
Here’s how the injection molding process is streamlined to minimize waste and maximize consistency:
- Preparation: Raw plastic pellets are dried and, if needed, mixed with pigments or colorants for precise color matching.
- Feeding and melting: Dried pellets are loaded into the machine’s hopper where they’re heated and mixed with a reciprocating screw until molten.
- Injection and cooling: Molten resin is injected into a custom mold under high pressure, then rapidly cooled to retain its shape.
- Ejection and inspection: Finished parts are ejected, inspected, and prepared for your use.
This process ensures reliable results, batch after batch

What Our Customers Say
Feedback and reviews from our clients.
Coming to see the factory has been very helpful. I came to China for the first time in January when I did a factory visit, checked out Star and their capabilities. I was really impressed by how they ran their operations, the quality control and everything else. That gave me a lot of confidence in their ability to do high-quality work.
Harvey
HoCOO of Gate Labs
I was impressed with the company on many levels, not just the exceptional cleanliness of the work areas but also the equipment quality and more than anything else the team spirit amongst the international and local engineers.

Common Questions
Frequently Asked Questions About Plastic Injection Molding
Find answers to common questions about injection molding manufacturing, mold design, and how industries like medical, electronic, agriculture, and consumer products can achieve their goals.
What are injection molding services?
Plastic injection molding services produce high-quality parts quickly and efficiently from a wide selection of resins, including high-density polyethylene (HDPE), acrylic, polypropylene, polycarbonate, and acetal or polyoxymethylene (POM). Procision Manufacturing specializes in injection molding projects of all sizes, from on-demand prototyping to high-volume production, ensuring low-cost solutions with no minimum order requirements.
What is the injection molding process?
Injection molding begins with drying raw plastic pellets, which may be blended with colorants. These pellets are melted and mixed inside the injection molding machine, forming a semi-liquid resin. The resin is injected under high pressure into a custom mold, filling the cavity to create the part. Once cooled, the part is ejected and the cycle repeats. Insert molding can also be integrated to enhance the final product’s functionality.
What are the advantages of injection molding?
Your precision parts will benefit from careful mold design and manufacturing which yields excellent surface finishes, tight tolerances, and material versatility to suit your needs.
What are the main cost drivers for plastic injection molding?
Costs vary based on a number of factors, such as mold complexity, material, and production volume. While higher volumes reduce per-unit costs, Procision’s low-cost solutions also ensure affordability for low-volume productions and prototyping.
What should you expect from a plastic mold manufacturer?
A reputable plastic mold manufacturer ensures every step of the process is meticulously controlled for consistent, high-quality results. This starts with the accurate identification of raw materials and continues through each phase of production to guarantee process repeatability. Full ISO certification is a testament to their dedication to quality and operational excellence.
How long does it take to make an injection mold tool?
The cost of a plastic injection mold tool can be a significant percentage of the total order for small volumes. However, this cost can be amortized over larger volumes so that it doesn’t become an issue. Rather, plastic resin and cycle times become the main cost drivers for larger volumes.
How can I reduce mold costs?
While it’s tempting for a project developer to prioritize upfront savings, opting for a low-cost mold tool often leads to poor quality, reduced durability, loose tolerances, and subpar surface finishes. These are not cost savings — they’re expensive mistakes. Instead, focus on long-term savings through production efficiency, faster cycle times, and stable processes. Over time, as production increases, the relative cost of a high-quality tool becomes negligible.

Common Questions
Procision Plastic Injection Molding Service FAQ
How long does it take to make an injection mold tool?
This depends on the complexity of the tool design and the type of material the tool is made from. Generally speaking, a very basic square shape made from relatively soft steel such as P20 can be made in less than one week. Very hard steels take longer to cut and to heat treat, while complex shapes or advanced surface textures can require three or more weeks to prepare.
What should you expect from a plastic mold manufacturer?
A reputable manufacturer will positively identify all incoming raw materials, and will carefully control every stage of production to ensure process repeatability. Full ISO certification is a good demonstration of their commitment to excellence.
How can I reduce mold costs?
A product developer should be looking to save money on the cost of a mold tool. In most cases, a less expensive tool is going to be of poorer quality, less durable, with looser tolerances and a bad surface finish. These are not cost-savings. Instead, they’re expensive mistakes. Rather, savings can be made long-term through production efficiency, fast cycle times, and process stability. As volumes increase, the relative cost of the tool goes down until it’s almost free.
