Resilient Flooring Mold - Precision Molding Technology Solutions by Yige

I. Core Technical Features

Resilient flooring molds are critical equipment in polyvinyl chloride (PVC) flooring production, with their design and manufacturing quality directly determining the product's quality, precision, and service life. The inherent properties of PVC materials dictate that molds must possess four core technical characteristics:

1. High-Precision Forming Capability

PVC flooring products require strict dimensional tolerances (e.g., medical tubing errors ≤0.01mm). Molds must ensure cavity dimensional accuracy through precision machining to prevent product deformation or assembly failure. Utilizing five-axis machining centers for precision processing, cavity accuracy is controlled within ±0.02mm, ensuring seamless flooring connections.

2. Strong Corrosion Resistance

To address hydrogen chloride gas generated during PVC decomposition, mold materials prioritize corrosion-resistant options such as 718H pre-hardened steel and S136 stainless steel. Surface treatments like chrome plating or electrolytic polishing extend mold lifespan by 3-5 times, exceeding 800,000 cycles.

3. Precise Thermal Management System

PVC has a narrow melting temperature range (160-200°C), with decomposition occurring above 200°C. Molds are equipped with zoned temperature control and efficient cooling systems to maintain cavity temperature differences within ≤±2°C, ensuring molding efficiency and product quality. The cooling system adopts conformal design with water channel spacing controlled at 20-30mm, improving cooling efficiency by 30%.

4. Optimized Runner Design

To address PVC melt's high viscosity, runners employ smooth curved structures to reduce flow resistance and ensure uniform cavity filling, avoiding defects such as short shots and air bubbles. Synchronized 16-32 point injection ensures uniform density of reinforcement ribs, achieving compressive strength of 8-12 tons/㎡.

II. Key Design and Processing Technologies

1. Material Selection and Compatibility

For standard PVC products, P20 tool steel may be selected, while high-end medical or highly corrosive applications prioritize 718H and ASP-60 powder high-speed steels. Hardness is maintained between HRC33-62 to balance wear resistance and machinability. The material system employs pre-hardened 718H mold steel (HRC 36-38) paired with carbide inserts.

2. Structural System Optimization

• Demolding mechanisms utilize multi-point synchronized ejection to address PVC's tendency to stick, with ejection pin density of at least 2 per 100cm²

• Vent hole dimensions are set at 0.03-0.05mm to prevent gas entrapment

• Cooling systems adopt conformal design with water channel spacing controlled at 20-30mm

3. Precision Machining Processes

High-speed milling and EDM achieve high-precision cavity forming, with wire-cut machining accuracy reaching ±0.005mm. Surface polishing combined with nitriding processes reduce cavity roughness to Ra≤0.08μm, enhancing product surface finish. PVD coating technology extends mold lifespan beyond 800,000 cycles.

III. Application Scenario Customization Solutions
