HDPE (High Density Polyethylene or Polythene) is produced at low pressure and can be exposed to temperatures of up to 90 °C. This plastic is characterised by a low degree of branching. This means HDPE has a high crystallinity, which means the plastic has a relatively high modulus and the highest density among the PEs. HDPE is food safe, has a high toughness and is resistant to water and fats. This is why HDPE is a popular material for packaging.
HDPE injection moulding
HDPE injection moulding is often used for products that must have a long lifespan, such as automotive parts, toys or computers and technical products. It is possible to add additives and to make products, shaped components or housings UV resistant.
Some of the advantages of HDPE:
- High shrinkage
- Very easy to process
- Excellent gliding characteristics
- High impact resistance at low temperatures
- High wear resistance
- Resistant to chemicals
- Resistant to fats
- Food safe (FDA approved)
- Water repellent
- Durable and sustainable
- Suitable for bulk products

When can HDPE be used?
HDPE is strong, repels fats and water and is sustainable. This is why this plastic is encountered in many sectors, including the food industry, packaging industry, infrastructure, leisure, agriculture, the automotive industry and civil engineering. You can use HDPE for applications including:
- Cutting plates and boards
- Loading containers, sliding and punching plates
- Valves for industrial fluids
- Vessels and storage tanks for chemicals and fuel
- Pipes for the transport of water, sewerage, gas and oil
- Blow moulded bottles for milk/juice, lids and caps
- Waste containers
- Terracing planks made from wood/polymer compounds
Finishing and assembly
HDPE can be processed in various ways. You can find more information about finishing and assembly at HSV Technical Moulded Parts, including painting, welding, assembly etc., on the assembly page.
What does HDPE injection moulding cost?
Would you like to learn more about the costs of HDPE injection moulding your plastic product, shaped component or housing? Request the Plastic QuickScan. The results of the QuickScan are used to assess the feasibility of your product design, and you will receive advice from our plastic experts and an initial estimate of the costs.
At HSV Technical Moulded Parts, we are fully committed to the use of sustainable raw materials and sustainable production of your plastic products, shaped components and housings, as well as the recycling and reuse of plastics.
HDPE is one of the most sustainable plastics of its kind. In addition to its long lifespan, the material is fully recyclable. This fits perfectly with our organisation’s environmental vision and the circular economy. Read more about our sustainable initiatives.
Injection moulding of large plastic products
HSV Technical Moulded Parts specialises in the injection moulding of large plastic products, shaped components and housings. Various thermoplastics and additives are used for this, including HDPE (High Density Polyethylene or Polythene).
