HDPE injection molding involves melting the HDPE material and injecting it into a mold cavity to create specific shapes.

This process is crucial for manufacturing a range of products like plastic bottles, containers, pipes, and automotive parts.

Injection molding is one of the main processes for manufacturing plastics. It is widely used for mass production of identical parts with strict tolerances. This is a cost-effective and highly repeatable technology that can produce high-quality parts for mass production.

This is a fast and intensive process that requires molten material to be injected into the mold at high temperatures and high pressure. The molten material depends on the scope of the manufacturing project. The most popular materials are various thermoplastics, but metals and ceramics can also be injection molded. The mold consists of a cavity that can hold the injected molten material and is designed to closely reflect the final characteristics of the part.

This means that the variable cost of production is lower, the design for manufacturing injection molding and process becomes more efficient, and as the cost is distributed among hundreds or thousands of parts, the cost of each part decreases as the output increases.

Since the cost is dispersed among hundreds of parts, injection moulding is an ideal process for mass production of plastic parts economically.

According to the requirements of the final part, a variety of plastics can be used for injection molding, including ABS, PS, PE, PC, PP or TPU. The procurement cost of mould materials varies according to the material selected. The cost of thermoplastic pellets is approximately US$1 to US$5 per kilogram. The material cost is defined by the design of the model, the material selected, and the amount of material used to perform the injection molding.

The cost of simple low-volume 3D printing molds may be as low as $100, while the cost of designing and manufacturing complex molds for mass production may reach the $100,000 mark. Although the fixed start-up cost is considerable, the variable cost of the injection molding process is lower due to the cheap thermoplastic materials, short cycle times, and gradual reduction in labour demand due to automation and economies of scale.

HDPE is an excellent choice due to its versatility, cost-effectiveness, and superior properties. Langgeng Jaya will help you to choose the right HDPE granules and flakes for your injection molding needs.
