Products Description

A refrigerator shelf is a core internal component designed to adapt to different fridge models while meeting the practical and safety needs of food storage.

Core Functions

1.Partitioned food storage – Prevents stacking and cross‑contamination of odors.

2.Perforated structure – Ensures even airflow between layers, maintaining a stable internal temperature.

3.Appliance‑grade load capacity & temperature resistance – Suitable for both refrigeration (0–10°C) and freezing (below -18°C) zones.

This refrigerator shelf helps you keep your fridge organized, your food fresh, and your kitchen efficient.

Main Materials

Metal Material: Primarily 304/201 stainless steel or chrome-plated iron wire, must pass salt spray rust prevention tests, strong load-bearing capacity, suitable for long-term heavy-duty scenarios such as the freezer compartment.

Plastic Material: Uses food-grade PP (polypropylene) or ABS resin, must comply with GB 4806.7 food safety standards, resistant to low-temperature impact, and often has an antibacterial surface treatment, suitable for the refrigeration compartment.

Core Process Flow

Metal Mesh Frame (Taking Stainless Steel as an Example)

Raw Material Pretreatment

Stainless steel coils are leveled, cut into fixed‑width strips, and cleaned to remove oil and oxide layers. This ensures effective rust prevention in later steps.

Raw Material Pretreatment

Stainless steel parts receive electrolytic polishing or passivation. Iron wire components are chrome‑plated (≥8μm) or electrostatically powder‑coated (≥60μm). All pass a 48‑hour salt spray test for rust resistance.

Edge & Accessory Assembly

Frame edges are rounded to prevent scratches. Standardized clips and support feet are installed to fit refrigerator liner slots, ensuring smooth assembly and disassembly.

Appliance‑Grade Quality Inspection

Every refrigerator shelf undergoes load‑bearing tests (no deformation after 48 hours at full rated weight), dimensional accuracy checks (compatible with specific fridge models), and surface smoothness inspection (no burrs or scratches).

Plastic Mesh Frame

Raw Material Preparation

Food‑grade PP/ABS granules are blended with color masterbatch and antibacterial agents (silver ion). The mixture is dried to remove moisture, preventing bubbles during injection molding.

Injection Molding

High‑precision molds (±0.1mm tolerance) inject molten plastic under 15‑30MPa pressure. After cooling and solidification, the frame blank is demolded.

Edge Deburring

Automated ultrasonic cutting removes burrs from parting lines, delivering a smooth, appliance‑safe surface.

Enhanced Functionality

Lorem iqsum is simply free Optional antibacterial coating (tested to JIS Z 2801, ≥99% antibacterial rate) or a "Food Contact Use" marking
