What is High-Density Polyethylene (HDPE)?
High-density polyethylene (HDPE), or PEHD, is a thermoplastic polymer polymerized from ethylene, a petroleum byproduct. It is a low-cost thermoplastic with a linear structure and very low or almost no branching. It is produced at relatively low temperatures (70-300°C) and pressures (10-80 bar). Furthermore, HDPE has two sources: modified natural gas (a mixture of methane, ethane, and propane); or from crude oil catalytic cracking. Currently, most high-density polyethylene (HDPE) products are produced using slurry polymerization or gas-phase polymerization processes. These processes first polymerize ethylene monomers in a solution, followed by separation and drying.

Moisture Resistance
Extremely low water absorption, maintaining dimensional stability even in humid environments.
Lightweight Design
Low-density material reduces product weight while maintaining structural integrity and strength.
Environmentally Friendly
100% recyclable material, supporting sustainable production and environmental protection.
Affordable
A cost-effective material with excellent performance-to-price ratio, suitable for high-volume production.
What is HDPE Molding?
First, HDPE plastic is melted into a moldable molten state. Once the resin reaches a molten state in the injection molding machine, the molten HDPE material is injected into the mold. The plastic resin hardens almost immediately after injection. After the part cools and solidifies, the mold is opened, and the part is removed. The mold is then reinstalled, and the process is repeated. Elimold uses only high-strength steel in manufacturing HDPE injection molds. This high-strength steel ensures that the molds can withstand hundreds of thousands of cycles of wear.
High-density Polyethylene in Injection Molding
Leveraging our expertise in HDPE plastic molding, we provide scalable solutions for industries that require durability, chemical resistance, and cost-effectiveness.
HDPE 5000S
HDPE 5000S boasts excellent tensile strength of 30 MPa and high elongation at 600%, an impact strength of 30 J/m, a heat deflection temperature of 85°C, low shrinkage (1.5%), and shape retention during cooling, contributing to the precise and consistent production of precision parts.
HDPE 6000F
HDPE 6000F exhibits superior melt flowability, with a tensile strength of 27 MPa, a flexural strength of 45 MPa, an impact strength of 35 J/m, and a heat deflection temperature up to 90°C. Therefore, this material possesses excellent mechanical properties, strong impact and shock resistance, and is suitable for applications facing moderate thermal challenges. It is ideal for manufacturing precision parts with complex geometries.
HDPE 7000F
HDPE 7000F boasts a flexural modulus of up to 1300 MPa and an elongation at break of up to 500%. Its higher molecular weight further enhances its mechanical properties and durability. This material combines flexibility and strength, making it suitable for products requiring both, and it excels in applications demanding high rigidity and structural integrity.
HDPE 8000F
HDPE 8000F features an impact strength of up to 50 J/m, a heat distortion temperature of up to 100°C, and a shrinkage rate as low as 0.8%. This material stands out for its excellent resistance to stress cracking, making it a representative of high-performance grades. It also exhibits excellent impact resistance, seismic resistance, and high-temperature resistance.

High-Density Polyethylene Injection Molding Experts
No matter the order size or design complexity, our team is dedicated to meeting your needs. We excel at producing parts according to your drawings, specifications, or purchase order requirements, and can also help you turn your brilliant ideas into finished products. If you haven’t yet received approval for your design, we’d love to collaborate with you to develop a prototype for testing and validation. Once the design is accepted, full-scale production can begin. Obtaining HDPE injection molded parts that meet your requirements may involve multiple processes. If your supplier cannot complete these processes, it may be necessary to transfer semi-finished products between different factories. This can extend lead times and reduce profit margins. Therefore, Elimold provides a variety of value-added services to its customers. You can rest assured that we will provide you with turnkey parts ready to use.
HDPE Injection Molding Quality Control
Elimold boasts an ISO 9001 certified workflow, with rigorous material testing as the first step in our quality control process. Our quality checks span the entire production process, beginning with First Article Inspection (FAI), hourly dimensional checks using calipers and gauges, and a 100% visual inspection of the final parts. Coordinate Measuring Machine (CMM) measurements verify critical dimensions against your drawings. Comprehensive documentation ensures traceability; each batch has a unique ID containing complete processing parameters, inspection results, and material certifications, eliminating concerns about consistency between different production batches.
