Plastic Injection Molding – HAOSTAMPING Custom Stamping Parts

Plastic Injection Molding Service

Injection molding is the most extensive and cost-effective way to make a large number of plastic products, example includes chairs, toys, cases for consumer electronics and so on, from the minor components to entire body panels of cars. Dozens of materials, insert molding, compression molding, and more options are available.

Rapid plastic injection molding is one of the most significant businesses in HAOSTAMPING. We can provide on-demand manufacturing from prototype to production. With over 20 years of experience in this field, we have the capacity for all your manufacturing projects of any size or complexity and offer competitive pricing, high-quality parts, and quick lead times on injection molding services.

The Process of Injection Molding

Plastic injection molding is the most common method for mass manufacturing of plastic products. How does it work?

The process of injection molding mainly includes the following steps:

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.

This process is repeated hundreds or thousands of times quickly, which amortizes the cost of tooling and reduces the cost of each unit to a few dollars or less. In HAOSTAMPING, the tool may contain a single cavity or hundreds of cavities to make indefinite parts. Depending on the material, size, and complexity of the part, the manufacturing cycle is different.

Plastic Injection Molding Materials

We have a strong supply chain that can provide the best materials for your project. All injection molding materials are from the manufacturers or their authorized agents, and we can provide the technical datasheet for each material. That will avoid any potential problem from material source. Generally if there is no especial specification on material, we suggest customer use our recommended stock material that will be faster and more cost-effective. If customers have special request, we can also use special materials for manufacturing.

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

Benefits of Rapid Injection Molding

Rapid 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 business 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

Automotive

Aerospace

Medical equipment parts

Electronics

agriculture

Addition Injection Molding Options

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

Structural foam molding:

Structural foam molding is a manufacturing process that is used to produce high-quality, lightweight parts for a wide range of applications, including medical devices. In this process, a plastic resin is mixed with a foaming agent and then injected into a mold, where it expands to fill the mold and create a foam-like structure.

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.

Injection Molding FAQs

So far, there is over 20 advanced injection molding machines in Chinese Brand from 60 to 1000 tons .In order to meet the different requirement of customers, our equipment is still constantly updated. Generally we can provide thousands of parts in 5 days if there is stock material after we receive customer’s order. Click here to visit our equipment list.

In principle, injection molding is an intricate and complex process. An injection molding machine has three main parts: the injection unit, the mold, and the clamp. Plastic pellets in the hopper feed into the barrel of the injection unit. Inside the barrel, a screw transport the pellets forward. Heater bands wrapped around the barrel warm up the plastic pellets. As the pellets are moved forward by the screw, they gradually melt, and are entirely molten by the time they reach the front of the barrel. Once enough molten plastic is in front of the screw it rams forward like the plunger of a syringe. In a matter of seconds, the screw injects the molten plastic into the empty part of the mold called the cavity image. The plastic solidifies in under a minute, the mold pens and part is ejected. The mold then closes, and the process repeats.

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.

We have no minimum order quantity. We can quote base on required batch quantity.
