Our HDPE Injection Molding Process
HDPE pellets are dried to remove moisture and prevent defects, then fed into the injection molding machine's hopper.
The HDPE pellets are heated to their melting point inside the barrel, where they are plasticized into a molten state.
The molten HDPE is injected into a precisely machined mold cavity under high pressure, filling the entire mold quickly and evenly.
Once injected, the mold is cooled, allowing the HDPE to solidify and take the desired shape of the part or component.
After sufficient cooling, the mold is opened, and the formed part is ejected using ejector pins or automated systems.
Excess material, such as sprues or runners, is trimmed, and the part undergoes quality checks to ensure it meets dimensional and strength requirements.

Having Doubts? Our FAQ
Check all our Frequently Asked Question
The cooling rate of HDPE is affected by several factors, including mold design, the part's wall thickness, and the temperature of the cooling channels. Thinner sections cool faster than thicker ones, while optimale cooling channel design ensures even heat dissipation.
The molecular weight of HDPE affects its viscosity during melting and flow characteristics. Higher molecular weight grades can improve mechanical strength but may require higher temperatures and pressures for effective injection, influencing cycle times and part quality.
Injection speed is crucial for preventing defects such as short shots and voids. A controlled injection speed ensures that molten HDPE fills the mold cavity uniformly, reducing turbulence and minimizing air entrapment, which can compromise part integrity.
Different grades of HDPE offer varying mechanical properties, such as tensile strength, impact resistance, and flexibility. Selecting the appropriate grade based on the application requirements is essential to ensure that the final product meets performance expectations.
Mold design for HDPE should consider factors like part geometry, draft angles, and cooling channel placement. Properly designed draft angles facilitate easy part removal, while strategically placed cooling channels promote consistent cooling rates, reducing warping and improving dimensional stability.
