Foundry Pattern Bolster With Quick Change System And Air Lift Holes Available To Reduce Downtime On Automated Molding Lines

KAILONG Foundry Pattern Bolster – Professional Overview

The KAILONG Foundry Pattern Bolster is a precision-engineered support plate designed to securely mount and align sand casting patterns, core boxes, and gating systems on molding machines or matchplate equipment. As a critical tooling component, the pattern bolster ensures accurate pattern positioning, repeatable mold registration, and extended service life under demanding foundry conditions.

Manufactured from high-grade cast iron (e.g., GG30 or equivalent) or heavy-duty fabricated steel, KAILONG bolsters undergo rigorous stress-relieving and age-treatment processes to eliminate internal strains and guarantee long-term dimensional stability. The working surfaces are precision-machined with a flatness tolerance of ≤0.1 mm/m and feature precisely located dowel holes, bushings, and clamping slots to accommodate standard pattern plates or loose patterns. For automated molding lines, optional quick‑change systems and air‑lift holes can be integrated to reduce downtime.

Key design features include hardened wear strips to resist abrasive sand flow, ribbed underside construction for maximum rigidity with reduced weight, and corrosion‑resistant coatings for prolonged service in moist or chemically active environments. Each bolster is custom‑manufactured to match specific molding machine specifications (e.g., DISA, Hunter, Sinto, or Jolt-Squeeze machines), ensuring seamless integration.

KAILONG’s advanced CNC machining centers and CMM inspection protocols guarantee interchangeability and repeatability across multiple bolsters. Typical applications include high‑production automotive casting, agricultural machinery parts, and valve bodies where consistent mold half alignment is essential. By minimizing pattern deflection and wear, the KAILONG Pattern Bolster significantly improves casting dimensional accuracy, reduces scrap rates, and extends pattern life. With over two decades of foundry tooling experience, KAILONG delivers robust, tailor‑made solutions that enhance productivity and reliability in metal casting operations worldwide.
