Plastic injection molding is a manufacturing process used to produce large volumes of plastic parts. The injection molding process involves injecting molten plastic material into a mold cavity, where it cools and solidifies into the desired shape. Then eject the molded plastic part. This method is widely used because it can create complex shapes with high precision and consistency, making it ideal for mass production. The injection molding services, in addition to the rapid completion of bulk plastic parts, also have a lower cost of characteristics.

At HordRT, plastic injection molding service is a core service. With over 11 years of experience, we provide on-demand manufacturing from prototype to production. As an injection molding manufacturer, we handle projects of any size or complexity, delivering high-quality parts, competitive pricing, and quick lead times. Andwe have no minimum order.

How Custom Plastic Injection Molding Works

Key Steps in Plastic Injection Molding:

  • Setting up the mold to the injection molding machine.
  • Feeding and melting the thermoplastic
  • Injecting the plastic into the mold.
  • Holding and Cooling.
  • Ejecting and Finishing processes.

The injection molding process can be repeated hundreds or thousands of times rapidly, which helps amortize the cost of tooling and reduces the cost of each unit to just a few dollars or less. At HordRT, our tools may feature a single cavity or hundreds of cavities, allowing for the production of countless parts. The manufacturing cycle varies based on the material, size, and complexity of the part.

Plastic Injection Molding Materials

Our robust supply chain ensures that we source the highest-quality materials for your project. We work directly with manufacturers and their authorized agents to provide you with top-grade injection molding materials, accompanied by detailed technical datasheets for each. This approach helps prevent potential issues related to material sourcing. For standard applications, we recommend our stock materials, which are both cost-effective and efficient. However, if your project requires specialized materials, we can accommodate those needs to meet your exact specifications.

The following materials are the most commonly used for plastic injection molding:

ABS
PC/ABS
TPU
PP
HDPE
TPU
PCTG
PSU
PC
POM
PA66
PBT
Nylon
TPV
PPE
PPA

Benefits of Injection Molding Service

Injection molding is the fastest and most cost-effective way of manufacturing hundreds and thousands of finished plastic parts. And it is one of the most popular businesses in our company. There are lots of advantages of rapid injection molding.

Fast production and highly efficient

The injection molding process is highly efficient, which can produce an incredible amount of parts per hour.

A large number of materials are available

There is a wide range of materials are available. Ability to use multiple plastic material simultaneously. Commonly used materials including acrylonitrile butadiene styrene (ABS), polyethylene (PE), polystyrene (PS), and polypropylene (PP).

Scalability and repeatability

One of the main benefits of plastic injection molding is its high repeatability. An aluminum mold will generally last between 5,000 and 10,000 cycles, and a full-scale steel production mold can last for over 100,000 cycles.

Cost-effective

The injection molding process is repeated hundreds or thousand of times quickly, which an amortize the cost of tooling and reduce the cost of each unit to a few dollars or less.

Common Applications 

Injection molding is used in many industries. Our expert team provides production solutions to accelerate your product to market.

Addition Injection Molding Options

In addition to the basic injection molding service, we also provide Over-molding and Insert Molding.

Over-molding

Over-molding, also known as two-shot, multiple-material molding, two-shot, or 2k molding, is a unique custom injection molding process that combines multiple materials seamlessly into a single part or product. It typically includes a rigid, plastic-base component overlaid with a thin, pliable, rubber-like thermoplastic elastomer (TPE) exterior layer or other materials using either a single-shot (insert molding) or two-shot (multiple-shot molding) technique. The over-molding process may be an excellent option for your next project after considering its significant advantages.

Insert Molding

Insert molding, also known as metal insert molding or plastic insert molding, is commonly used to add metal parts to injection molded parts during molding rather than after the parts have cured, cutting down on post-molding manufacturing/assembly operations.

Insert Molding

Insert molding, also known as metal insert molding or plastic insert molding, is commonly used to add metal parts to injection molded parts during molding rather than after the parts have cured, cutting down on post-molding manufacturing/assembly operations.

Injection Molding FAQs

We currently have over 50 advanced Chinese-brand injection molding machines, ranging from 60 to 1000 tons. To meet our customers' diverse requirements, we continually update our equipment. Typically, we can produce thousands of parts within 5 days if the material is in stock after receiving an order. Click here to view our equipment list.

Injection molding is a manufacturing process used to produce large volumes of plastic parts with high precision and consistency. Here is a detailed overview of the key steps involved:

1. Clamping
  • The injection molding machine consists of two main parts: the injection unit and the clamping unit.
  • The mold, which consists of two halves, is mounted on the clamping unit. The clamping unit securely closes the mold, ensuring it stays in place during the injection process.
2. Injection
  • Plastic pellets are fed into the injection unit, where they are heated and melted by a combination of heat and pressure.
  • The molten plastic is then injected into the mold cavity through a nozzle and runner system under high pressure. This high pressure ensures the mold cavity is completely filled with plastic.
3. Cooling
  • Once the mold cavity is filled, the plastic begins to cool and solidify into the shape of the mold.
  • Cooling time varies depending on the material and part design. Efficient cooling systems are often used to speed up this process and ensure uniform cooling.
4. Ejection
  • After the plastic has cooled and solidified, the clamping unit opens the mold.
  • Ejector pins or plates push the finished part out of the mold cavity. This step may involve automated systems to ensure safe and efficient part removal.
5. Finishing
  • The ejected part may require additional processing, such as trimming excess material (known as flash) or performing secondary operations like painting, coating, or assembly.
  • Quality control checks are often conducted to ensure the part meets specifications and standards.

It depends on the material, size and complexity of the part. Generally, tools can be finished in 10-25 days. If it is urgent, tools can be finished with 1 week.

There is no minimum order quantity. We offer quotes based on your specified batch size.
