Products Description
⚙️ I. Mechanical Structure Advantages
High-Precision Clamping & Injection System
Micro-Clearance Mold Locking Design: Utilizes high-rigidity double-toggle or direct-pressure mechanisms with clamping force repeatability of ±0.5%, preventing micro-shifts during high-speed cycles to eliminate flash on precision threads or snap-fit structures.
Low-Inertia Injection Unit: Optimized inertial mass enables millisecond-level response (e.g., 0.3s injection time), meeting strict timing requirements for thin-walled (0.5~1.2mm) multi-cavity cosmetic parts.
Cleanroom-Grade Protection Design
Fully Enclosed Guide Pillars & Dust Covers: Critical moving parts feature stainless steel bushings + multi-layer seals to isolate lubricants from plastic dust, complying with GMP cleanroom standards.
Corrosion-Resistant Surface Treatment: Platens and tie bars coated with Teflon or electroplated to resist chemical corrosion from cosmetic raw materials (e.g., acidic colorants, fragrance additives).
⛽ II. Hydraulic System Advantages
Ultra-Precise Flow & Pressure Control
Closed-Loop Servo Proportional Valves: Flow control accuracy ±0.1%, supporting multi-stage injection (5~8 speed/pressure phases) to precisely fill micro-runners and embossed textures while minimizing weld lines.
Independent Accumulator: Delivers instant power for high-speed injection (≥300mm/s), ensuring gloss surfaces without flow marks.
Low-Contamination & Temperature Stability
Zero-Leakage Sealing Technology: FKM seals + hard-chrome-plated cylinders prevent hydraulic oil mist contamination.
Dual-Mode Temperature Control: Water-cooled oil system (±1°C fluctuation) + auxiliary air cooling maintains consistent viscosity for stable valve response.
🔩 III. Screw & Barrel Design Advantages
Low-Shear Plastication System
Low Compression Ratio Screw (1.4~1.6:1): Shallow flights reduce shear heat, preventing thermal degradation/yellowing of transparent materials (e.g., PETG, AS).
Barrier-Type Mixing Head: Enhances melt homogeneity to eliminate "streaking" from uneven pigment dispersion.
Wear & Corrosion Resistance
Bimetallic Barrel (Nickel-Alloy Liner): Hardness HRC≥60 withstands abrasion from glass-filled materials (e.g., cosmetic caps).
Chrome-Plated Screw Surface: Reduces adhesion of engineering plastics (e.g., PPA), minimizing cleaning frequency.
Precision Temperature Control
6~8-Zone Barrel Heating: Independent PID control per zone (±0.5°C) matches low-thermal-sensitivity materials (e.g., PMMA), preventing degradation.
Ceramic Heaters + Air Cooling: 40% faster thermal response for frequent material changes.
✨ IV. Additional Optimizations
Micro-Injection Control: 0.01g dosing accuracy for micro-scale parts (e.g., mascara brush heads).
Modular Quick-Change System: Swap screws/molds within 30 minutes for flexible small-batch production.
Clean Gas Assist: Nitrogen purging for hopper and mold cavity prevents material oxidation/discoloration.
