Technical Specifications & Mould Structure

Our Refrigerator Crisper Drawer Moulds are built for durability and high-volume automation. Below is a breakdown of our standard Mould configuration:

Structural Design Details:

Feeding System: Direct injection via a one-point needle valve gate, ensuring beautiful breakpoints and minimal vestige.

Mould Base: The front Mould retains its original form for stability, while the back Mould is inlaid with precision Mould cores for easy maintenance.

Mechanical Action: Incorporates large angle lifters on one side and structured small angle lifters on both sides to form complex geometries without drag marks.

Why Choose Zhongyue’s High-Gloss Refrigerator Drawer Moulds?

Achieving a "mirror effect" on large appliance parts is challenging. Our design philosophy focuses on three core pillars to guarantee perfect parts every cycle.

1. Advanced Hot Runner & Valve Gate Technology

Weld lines are the enemy of transparency. To combat this, our Moulds feature:

Individual Nozzle Control: Each hot nozzle (typically 6–8 nozzles) is equipped with a sealing needle and an independent air channel.

Time-Sharing Injection: Using solenoids and time relays, we control the glue-feeding sequence for each nozzle. This advanced technique effectively controls or even eliminates weld marks and flow lines, ensuring optical clarity.

2. Precision Cooling & Heating System

Temperature consistency is key to preventing shrinkage and internal stress.

High-Temperature Oil Pipes: We utilize high-temperature-resistant oil pipes to withstand the 80–90°C environment without risk of bursting.

Optimized Water Channels: Cooling water runs through both the core and the angle lifters. By using extended water pipes instead of traditional seals, we prevent rubber ring aging under high temperatures, significantly reducing your long-term maintenance costs.

Resin Insulation: An insulation board is added to the fixed Mould side to minimize heat loss during operation.

3. Strict Product Structural Standards

For high-gloss surfaces, light refraction exposes even microscopic defects. We adhere to stricter design rules than industry standards:

Rib Thickness: Limited to ≤ 0.4x the main wall thickness (compared to the standard 0.6x) to prevent sink marks.

Bosses/Screw Posts: Special structural treatment is applied to ensure no cracking or deformation occurs during ejection or use.

Material Compatibility & Applications

Our refrigerator drawer Moulds are versatile and support a range of food-grade, non-toxic materials:

GPPS (General Purpose Polystyrene): For crystal-clear transparency.

PP (Polypropylene): For chemical resistance and flexibility.

PC (Polycarbonate): For high impact strength and superior surface permeability.

All Moulds are designed for fully automatic production, yielding parts that are bubble-free, crack-free, and environmentally compliant.

Frequently Asked Questions (FAQ)

Q: What is the biggest challenge in making a Refrigerator Crisper Drawer Mould?

A: The primary challenge is achieving a high-gloss, mirror-like surface without weld marks or sink marks. At Zhongyue Mould, we solve this through precise Mould temperature control (80-90°C) and a multi-nozzle hot runner system with sequential valve gating.

Q: How do you prevent the Mould from deforming under high temperature?

A: We reinforce the Mould structure and use high-temperature-resistant materials for all hydraulic and cooling lines. The addition of a resin insulation board also stabilizes the operating temperature.

Q: Can I use this Mould for different materials like PP and PC?

A: Yes. Our Mould designs are optimized for material versatility, including GPPS, PP, and PC, ensuring optimal gate vestige and cooling for each resin type.
