How To Work With Us
The plastic injection molding process may seem simple, but there are many parameters that need to be tightly controlled to ensure the quality and consistency of the plastic components produced.
Factors affecting the tolerance of injection molded parts include plastic properties, product design, mold design, injection molding process, etc. When we talk about injection molding product tolerances, it’s better to consider the appearance and function of the finished product and the cost.
Usually, Prototool takes DIN 16742 as our injection molding tolerance standard, and for the automotive industry, we comply with the QC-T-29017-1991 automotive industry tolerance standard as our standard. When the customer has special tolerance requirements, we strictly follow the requirements.
The Plastic Injection Molding Process
The core and the cavity are the two main pieces of an injection mold. In the first step, during clamping, these two parts of the mold will be extruded and fit together by the machine.
Next is the dwelling phase, where the melted plastic is filled to the entirety of the mold through pressure. The pressure is applied directly to the mold such that the liquid fills all mold cavities, and the product comes out accurately and is identical to the mold.
This process step allows the time needed for the mold to cool. If this step is performed too hastily, the products may stick together or become distorted when demolding.
5. Mold Opening
This is the opposite process of clamping. In this step, a clamping motor slowly opens the two parts of the mold to make for the safety and stability.
Materials Used for Plastic Injection Molding
Free & Quick
We offer multiple finishing options to complete the plastic products made with the plastic injection molding process. You can choose from any of the following depending upon your application’s requirements:
Interior, non-cosmetic finish according to the geometry of the mold.
Range of SPI finishes from Grade 3 diamond / high polish to 320 stone low polish. These Finishing options include SPI A-1, SPI A-2, SPI A-3, SPI B-1, SPI B-2, SPI B-3, SPI C-1, SPI C-2, SPI C-3, SPI D-1, SPI D-2, and SPI D-3.
We can install the most commonly used and popular standard inserts in UNF and metric sizes.
As the name suggests, the mold will remain ‘as it is’ – without any secondary texturing or polishing.
Creating textures on the molds so that it shows on the final product. This finishing option includes matte, swirls, patterns, and lines.
Engrave part numbers, designs, logos, or any other specified printing onto your parts.
Application of an ink-based design to the surface.
Painting the surface with standard colors or Pantone matching, including Primer and topcoat. Masking available; EMI (copper) paint.

What is Plastic Injection Molding?
Benefits of Plastic Injection Molding
Plastic injection molding offers various benefits for all industries. Some of its top benefits include:
- Ability to produce large volumes of parts quickly
Once the process has been set up and tested, plastic injection molding machines can produce thousands of items quickly and efficiently.
- High surface quality
This process can produce high-quality parts with consistency. Plastic injection molding typically produces parts that are strong, tensile, and highly detailed.
Once the mold has been built, the cost of production per component is relatively low, especially if created in high numbers.
Manufacturers can choose the mold design and type of thermoplastic, allowing them to produce a variety of components, including parts that are complex and detailed.
- Consistent and Repeatable
The process of plastic Injection molding can help produce thousands to millions of parts that are precise and accurately identical to the master mold.
Injection molding is a speedy, cost-effective, and exceptionally accurate manufacturing process that is typically used for the mass production of complex molded parts in various materials.
The time taken to create a plastic injection mold tool varies according to the complexity of the design and the possible heat treatment. However, typically, a plastic injection mold tool can be made anywhere between five days to two weeks.
Once an injection mold tool is made, plastic injection molding is the most rapid and cost-effective manufacturing process to produce large numbers of finished plastic parts. The products made with this process have excellent surface finishes with consistent and repeatable dimensional tolerances.
There is a wide range of industries using plastic injection molding, including aerospace, automotive, medical devices, consumer goods, education, energy, electronics, robotics, toys, and more.
Yes, we offer multiple colors on the same material. However, this may cost a little extra.
