Our Advantages

1 High efficiency

It can be produced 24 hours and a large number of plastic parts can be produced in a short time. Our team will guide you through all steps of the injection molding process. Free DFM feedback.

 

2 High-strength components

The strength of the moulded parts can be enhanced by adding special fillers to the liquid resin. Strictly according to customer’s customized color production.

 

3 Low Cost

The repeatability of injection moulding usually results in low cost of each component. In addition, it provides low-cost aluminum rapid tooling options.

 

4 Ready-to-use:

As long as the mold is properly finished, the injection parts will be removed from the mold, and the appearance is smooth without further processing.

 

5 Detailed features

With the technical reserve of multi-cavity, complex mould and secondary injection moulding, high-pressure injection moulding is adopted, and injection resin can reach every sharp corner, allowing large-scale production of complex structural parts. Machine pressures range from 50 to 2,000 tons, providing all industry standard materials.

 

6 Strict Tolerances

Professional DDPROTOTYPE employees work tirelessly behind the scenes to ensure that your parts are manufactured on time and meet your precise specifications. We have passed ISO 9001 and ISO 13485 quality certification.

What materials do you use to make tools?


It depends entirely on the number of parts needed. The higher the expected number, the more difficult the tool material is to resist the wear of multiple moulding cycles. Although each case is unique, please refer to the following table as our starting point for your specific components:

If I need really high quantities of parts, what steps do you take to assure my parts are as inexpensive as possible?

We look at many different ways to assure the lowest cost parts possible.

1 We use well-engineered cooling systems to reduce the cycle time.

2 Where applicable, we use multi-cavity tools to meet large volume capacity and reduce part cost.

3 We often use hot tip gates, sub gates, hook gates, and automatic cutting gates to reduce labor cost.

4 We have mechanical arms and conveyor belts installed on our Injection Molding Machines to help handle the molded parts automatically and efficiently.

 

What is Rapid Molding and Injection Molding?

Rapid tooling is a form of rapid prototyping manufacturing, which involves the process of creating mould rather than part, and creating mould using rapid prototyping technology to create multiple copies of parts.

Aluminum or mild steel is generally used as the material for rapid tooling. This is one of the appropriate ways when traditional tools are either expensive or not necessary for the required parts or volumes. Therefore, this is a perfect way to minimize costs when market testing requires small batches and will not require large batches in the future.

Create Dies

DDPROTOTYPE often uses its experience in CNC machining to create dies, but it can also use 3D printing and other to create dies.

Injection moulding is the process of injecting molten resin materials into mould to produce large numbers of parts. Because of its high accuracy, repeatability and large-scale cost-effectiveness, injection moulding is used to manufacture products and components ranging from minimal medical plug-ins to large-scale automotive and aviation parts.

In the process of injection moulding, the resin material is heated and mixed, in which the reciprocating screw injects the melted resin material into the separate mould, then injects the material into the cavity under high pressure, cools in the cavity and solidifies into the appropriate shape to form the final plastic parts.

When used in conjunction with rapid tooling, injection moulding is very efficient and can create parts at low cost in a very short time.

 

The key steps of injection moulding process:

 

1 Clamping: Close both sides of the die and be sure to clamp.

2 Injection: The resin material is fed into the machine and pushed into the mould. The material melts due to heat and pressure and then injects plastic into the mold – this is called “injection”.

3 Cooling: The plastic in the die is cooled and solidified into the shape of the part.

4 Ejection: After the parts are cooled, they eject from the die.

Advantages of Injection Molding

Because of the high pressure characteristics of injection moulding process, it is much easier to manufacture parts with detailed features or complex geometric shapes, which are too expensive by CNC machining. The characteristics of repeated use of dies over a long period of time lead to extremely high productivity, which is more cost-effective and efficient than other manufacturing processes. Different injection moulding processes, such as cladding and insert moulding, allow you to create plastic parts with unique characteristics, such as enhanced strength, soft grip surface or increased flexibility.
