Thin Wall Injection Molding Services
IATF 16949 | ISO 13485 | ISO 14001
JUCHENG specializes in thin wall injection molding services, pushing the limits of polymer flow. We achieve sub-millimeter plastic molding with wall thicknesses as low as 0.3mm, utilizing high speed thin wall molding technology to ensure flawless parts for the electronics and medical sectors.
Superior Tooling for High-Speed Flow
Thin wall success is 90% mold engineering. Our in-house capabilities ensure zero-flash performance under extreme pressures.
5-Axis Precise Venting
Thin wall cavities trap air rapidly. We use 5-axis CNC and precision Wire EDM to machine microscopic vents (0.01mm) that allow air to escape while blocking molten resin.
Conformal Cooling
Uniform cooling is critical to prevent thin parts from "potato chipping" (warping). We engineer complex 3D cooling channels that follow the part geometry precisely.
Hardened Steel Cores
To withstand injection pressures over 20,000 psi, we build molds using premium S136 or H13 steels, heat-treated to 52-54 HRC for maximum tool life.
Precision Below 1.0mm
Thin wall molding is a specialized form of conventional injection molding that focuses on mass-producing plastic parts that are thin and light, without sacrificing structural integrity.
As electronic components shrink and medical devices demand lighter profiles, thin wall technology becomes essential. This process requires high injection pressures, high speeds, and most importantly, extraordinary mold precision to ensure consistent filling and prevent warpage.
Thin Wall Engineering Matrix
Achieving a high l/t ratio injection molding requires extraordinary precision. We utilize conformal cooling channel mold design and high-speed accumulators to fill thin wall plastic parts before the resin freezes, preventing flow hesitation.
| Parameter | Standard Molding | Jucheng Thin Wall Molding | Engineering Benefit |
|---|---|---|---|
| Wall Thickness | 1.5mm - 3.0mm | 0.3mm - 0.8mm | Lighter weight & less material |
| Injection Speed | Standard | Ultra-High (Accumulator driven) | Fills before resin freezes |
| Mold Steel | P20 / Soft Steel | Hardened H13 / S136 (52 HRC) | Handles 20,000+ psi pressure |
| L/T Ratio | < 100:1 | 200:1 to 300:1 | Complex, long-flow geometries |
