Custom LDPE Molding Solution
Zhongren specializes in custom LDPE injection molding for lightweight and chemically resistant components. With deep experience in low-density polyethylene injection molding, we produce reliable and cost-effective plastic parts for industries such as food packaging, healthcare, consumer goods, and electronics. LDPE injection molding offers excellent impact strength, moisture resistance, and toughness, making it ideal for products that require both flexibility and durability.
How Are LDPE Parts Manufactured?
We provide full-service LDPE injection molding, utilizing advanced tooling, precise process control, and comprehensive quality assurance measures to effectively manage LDPE’s low melt viscosity, slow cooling behavior, and associated processing challenges.
- LDPE Injection Molding
- LDPE Extrusion Molding
Due to its flexibility and shrinkage behavior, proper mold design, precise venting, and careful process control are critical to avoid warping, sink marks, and surface defects in injection molded LDPE parts.
Common Applications of LDPE Molding
Thanks to its flexibility, moisture resistance, and toughness, LDPE molding is widely used in:
- Medical device components and tubing
- Flexible packaging and dispensers
- Electrical insulation covers
- Consumer product housings
- Food-grade containers and bottle caps
- Toys and protective enclosures

FAQ of LDPE Injection Molding
Can LDPE be used for overmolding or insert molding?
Yes, LDPE injection supports insert and overmolding, though adhesion to other plastics or metals may be limited without surface treatment.
Is food-safe or medical-grade LDPE available?
Absolutely. We offer certified LDPE injection molding materials that comply with FDA and medical standards, suitable for direct food contact and disposable medical devices.
How does LDPE compare to HDPE or PP?
LDPE is softer and more flexible than HDPE and PP, with better impact resistance but lower strength and heat tolerance. It is ideal where flexibility and low cost are prioritized.
What is the lead time for custom LDPE injection molding?
Tooling typically takes 2–4 weeks. Once validated, production begins based on part complexity and volume. LDPE’s fast cycle times help shorten delivery.
