Plastic Injection Molding services

Plastic Injection molding is a common production process used to manufacture plastic parts from materials called thermoplastics. This process is typically used to produce plastic parts in large quantities. Plastic Injection Molding involves melting plastic and then injecting it into a mold, where it cools and solidifies, taking the final form as the desired plastic part.

This process can be repeated as required to produce thousands or even millions of the same part. Hence, the process of plastic injection molding allows manufacturers to create as many plastic parts as they want using just a single mold.

The Plastic Injection Molding Process

1. Clamping

The injection mold is usually made in two pieces. These two plates of the mold are pushed up against each other in a machine press during the first step, clamping.

3. Dwelling

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.

5. Mold opening

In this step, a clamping motor slowly opens the two parts of the mold to make for the safe and simple removal of the final product.

2. Injection

Once the two plates of the mold are clamped together, the actual process of injection can begin. The plastic, typically in the form of pellets, is first melted down to form a complete liquid. That liquid is then injected into the mold.

4. Cooling

In the cooling stage, the mold is left alone so the hot plastic inside can cool down and solidify into a usable product, as shaped by the inside of the mold.

6. Ejection

Once the mold is properly open, an ejector bar will gently push the solidified product out of the open mold cavity, revealing the final product for customer use.

Materials

tolerance

For our plastic injection molding services, we are typically able to maintain a machining tolerance of +/- 0.003 in. (0.08mm) with an included resin tolerance that can be more than but not less than +/- 0.002 in. /in. (0.002mm/mm).

Finishing

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:

Finishing

Standard Finish

Interior, non-cosmetic finish according to the geometry of the mold.

SPI Finishes

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.

Threaded Inserts

We can install the most commonly used and popular standard inserts in UNF and metric sizes.

As Molded

As the name suggests, the mold will remain ‘as it is’ – without any secondary texturing or polishing.

Mold Texturing

Creating textures on the molds so that it shows on the final product. This finishing option includes matte, swirls, patterns, and lines.

Laser Engraving

Engrave part numbers, designs, logos, or any other specified printing onto your parts.

Pad Printing

Application of an ink-based design to the surface.

Painting

Painting the surface with standard colors or Pantone matching, including Primer and topcoat. Masking available; EMI (copper) paint.

What is Plastic Injection Molding?

Plastic Injection molding is a well-designed and simple manufacturing process that can quickly produce intricate geometrical shapes for custom parts and products. It is a popular process of choice for companies looking to produce repeatable parts with strict mechanical requirements.

Plastic injection molding involves filling a mold tool with liquid plastic resin under great pressure. The tool may have only a single cavity or hundreds of cavities to make unlimited numbers of parts.

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.

  • Cost-Effectiveness

Once the mold has been built, the cost of production per component is relatively low, especially if created in high numbers.

  • Flexibility

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.

F.A.Q.

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.
