Quality Surface Grooved Hot Platen for Plywood Production Machinery

PRODUCTS INTRODUCTION:

The quality surface grooved hot platen is a high-precision, application-specific component developed exclusively for plywood production machinery. Its defining feature is the precision-machined grooves on the working surface.This platen is widely used in core plywood lamination, face veneer lamination, and multi-layer plywood pressing processes, directly contributing to the production of high-quality, high-strength plywood products.

KEY ADVANTAGES:

Precision Groove Structure for Adhesive & Heat Management: The surface grooves are designed with a uniform spacing and a precise cross-sectional shape (typically U-shaped or V-shaped, with a width of 2mm–5mm and depth of 0.5mm–1mm). These grooves serve two critical functions:

1. Adhesive Overflow Channel: During plywood pressing, excess adhesive (which can cause surface “glue spots” if left on the plywood surface) flows into the grooves, keeping the plywood surface clean and reducing post-processing (e.g., sanding) workload.
2. Heat Dissipation & Uniformity Enhancement: The grooves create micro-channels for heat circulation, preventing localized heat accumulation on the platen surface. This further improves the surface temperature uniformity (tolerance ≤2.5°C, better than the industry average of 3°C–5°C) and ensures that the adhesive in the plywood’s internal layers is fully cured.

High-Strength Surface for Wear Resistance: The grooved surface undergoes a precision grinding and hardening treatment (surface hardness ≥HRC 45), making it highly resistant to wear from repeated contact with plywood blanks and adhesive residues. This ensures that the groove dimensions remain stable over long-term use (service life ≥5 years under normal operating conditions), avoiding the need for frequent platen replacement.

Technical Specifications

Groove Precision: Groove spacing tolerance ≤0.1mm, width/depth tolerance ≤0.05mm; groove interior smoothness ≤1.5μm (easy to clean).

Heat Carrier & Channels: Compatible with oil/steam. Internal cross channels: 30mm (≥1500×2600mm large platens) or 25mm (medium platens), 90mm channel spacing.

Size & Installation: Standard sizes ; custom options available. Mounting hole position tolerance ≤0.1mm for seamless press alignment.

Application Value for Manufacturers  

Quality Upgrade: 90% reduction in surface defects (glue spots, uneven color); bonding strength meets standard.  

Efficiency Boost: 30% less post-pressing sanding time; 10–15% shorter pressing cycles, increasing production capacity.

Cost Savings: 50% lower platen replacement frequency vs. conventional models; easy-to-clean grooves cut maintenance labor & adhesive waste.
