The Heavy Putty Filling Machine is a high‑capacity coating solution engineered for filling and levelling porous substrates such as MDF (medium‑density fibreboard), calcium silicate boards, wood panels with coarse tubular fibres, and other flat materials using water‑based or UV‑curable fillers. It automatically fills surface pores and depressions to create a perfectly smooth base, while scraping away excess putty and recycling it on‑site – completely eliminating manual putty‑filling labour and significantly boosting production efficiency and yield.

1. Fully Automated Filling – No Manual Labour
   Automatically fills concave pores and levels the board surface in one pass, eliminating tedious hand‑scraping and drastically reducing rework rates.

2. Independent Frequency Control for Easy Adjustment
   Each roller – including the distribution roller, rubber roller, conveyor belt, and scraping roller – is driven by its own independent motor, reducer, and frequency inverter. This allows fine‑tuning of speeds to match different substrate types, filler viscosities, and process requirements, with simple on‑panel adjustments.

3. Anti‑Slip Conveyor Belt – Solvent‑Resistant & Durable
   Fitted with a corrugated anti‑slip conveyor belt that resists solvent attack and prevents slipping or delamination, ensuring stable, consistent workpiece feeding even with solvent‑borne coatings.

4. 100% Paint Recovery – Cost & Eco Efficiency
   An imported high‑performance air pump and integrated oil‑groove recovery system allow complete reclamation of excess filler. This achieves 100% material utilisation and reduces coating consumption by over 50% compared to manual spraying – delivering immediate cost savings and environmental benefits.

5. Premium Japanese Silicone Rollers – Long Service Life
   The coating roller is made from silicone rubber with raw materials imported from Japan, offering exceptional resistance to solvents and abrasion. This ensures consistent coating quality, excellent surface smoothness, and extended roller longevity.

6. Superior Finish Quality
   The machine delivers a smooth, plump, and colour‑consistent coating layer with no chromatic difference, enhancing the aesthetic and adhesion performance for final finishing coats.

7. Robust Independent Drive System
   Each roller and the conveyor are powered by separate motor‑reducer‑frequency units, guaranteeing best‑in‑class precision, stability, and repeatability over long production runs.

The machine operates via an air‑pump circulation system that delivers filler to the coating roller. The roller applies a uniform layer onto the flat panel surface, while a filling/scraping roller (set at a precise gap) removes excess putty – leaving only the material that fills the pores and depressions. The scraped‑off surplus is collected through a recovery trough and recycled 100% for immediate reuse, minimising waste.

• Substrates: Wood, MDF, particleboard, calcium silicate board, solid wood panels, and engineered wood.

• Coating materials: Water‑based putties, UV‑curable fillers, primers, and sealers.

• Typical end‑uses:

  • Furniture panels (tables, cabinets, doors)

  • Decorative boards and wall panels

  • Kitchen and bathroom cabinets

  • Construction boards (fibre cement, gypsum‑based panels)

The machine ensures a smooth, full‑bodied, and colour‑uniform surface, providing an ideal foundation for subsequent topcoats.
