Leader in precision plastic injection moulds: the cornerstone of creating excellent products

        In the plastic injection molding industry, we specialize in plastic injection mold design and manufacturing, providing you with outstanding solutions from initial concept to finished product.

Molds: The Epitome of Precision Craftsmanship

        Every plastic injection mold consists of a precisely matched cavity half (fixed half) and core half (moving half). The cavity half is securely mounted on the stationary platen of the injection molding machine, while the core half is installed on the moving platen. The mold cavity, formed when these two halves clamp together, is where molten plastic is accurately shaped.

I. Understanding Mold Structure: Mastering the Key to Quality

We meticulously craft every detail of the mold to ensure its efficiency, stability, and durability:

• • Robust External Structure：

    • Top and bottom clamping plates (fixed plates) along with the cavity plate, core plate, and support plates form the solid framework of the mold, withstanding injection pressure and clamping force to ensure molding accuracy.

    • The precise alignment of guide pillars and guide bushings guarantees accurate mold opening and closing, ensuring consistent product quality.

    • Mold feet (risers) provide stable support and facilitate installation and adjustment.

  • Core Molding Components：

    • Cavity inserts and core inserts: As critical components that directly determine the product's external appearance and internal structure, we use top-grade mold steel combined with custom design and high-precision machining to meet your stringent requirements for product appearance, dimensions, and surface finish.

    • Locating ring and sprue bushing: Ensure perfect alignment of the mold with various injection molding machines and guide the smooth flow of plastic into the mold cavity.

  • Efficient Internal Operation：

    • Cavity Side Internals: Locating blocks and locating pins ensure the precise fixation of mold inserts. A carefully designed parting line (PL surface) considers demolding and surface quality. Clamping slots provide secure locking, and eyebolt holes facilitate lifting and maintenance.

    • Core Side Internals: In addition to the core insert, the clever use of sliders and interchangeable inserts enables the creation of complex lateral holes or protrusions while ensuring ease of maintenance and extending mold life.

  • Smooth Ejection System：

    • Ejector pins, ejector plate, and ejector retainer plate form the core of the ejection system. We optimize the layout and size of ejector pins through CAE simulation analysis, coordinated with the precise resetting of return pins and coil springs, to ensure products are demolded perfectly without deformation or damage.

II. Tailored Mold Solutions: Two-Plate and Three-Plate Molds

We understand that different product characteristics require specific mold structures：

• • Two-Plate Molds: Simple in structure and cost-effective, especially suitable for large plastic parts or products where gate marks are not a primary concern.

  • Three-Plate Molds: By adding a runner stripper plate (intermediate plate), automatic separation of the runner from the product can be achieved. This design is perfectly suited for multi-point gating, small precision parts, and products with high aesthetic quality requirements.

Whatever your needs, we can design and manufacture high-precision two-plate and three-plate molds, providing the most optimized mold solutions.
