SUNMORE ROTO OEM Custom Cast Steel Rotomolded Blower Housing Mould, Plastic Fan Shell Rotational Mold With Square Integrated Lifting Frame & Quick Toggle Clamps is a professional cast steel rotational mold independently developed and manufactured by SUNMORE ROTO factory, specially used for mass production of hollow anti-corrosion plastic blower fan shells for industrial ventilation equipment.
This blower housing rotomold adopts thickened cast steel cavity with uniform and stable heat conduction. During the heating cycle of rotomolding equipment, heat spreads evenly inside the cavity to ensure consistent wall thickness of finished plastic fan shells, effectively eliminate molding defects such as bubbles, cold marks and sink marks. A square integral steel lifting frame is welded around the mold body, built-in lifting lugs for overhead crane hoisting, and the square frame provides stable supporting force when the mold is placed on shuttle rotomolding machines. Multiple heavy-duty toggle quick clamps are evenly arranged on the parting surface to realize rapid locking before production and fast opening after cooling demoulding. All inner and outer surfaces of the cast steel mold are treated with high-temperature resistant anti-rust coating, resisting long-term repeated high-temperature circulation inside heating ovens, hard to oxidize and deform, and residual plastic raw materials can be cleaned easily after batch production.
We provide full drawing OEM customization service. Customers can freely adjust fan shell outer outline, cavity size, internal mounting hole position layout, mold wall thickness and square lifting frame size according to blower housing design drawings. This mold has wide compatibility with all mainstream bi-axial shuttle rotational molding equipment on the market, applicable to various specifications of industrial ventilation fan plastic housing production.
Key Features & Benefits
Full Drawing OEM Personalized Customization: All structural parameters can be customized strictly according to customer technical drawings, including blower shell overall outline, cavity inner size, mounting hole distribution, mold wall thickness and square integrated lifting frame dimension.
Thickened Cast Steel Mold Cavity: Balanced heat conduction for flawless fan shell surface with smooth inner and outer surfaces without pits, flow lines or uneven wall thickness.
Square Integrated Lifting Frame: Provides stable support and convenient hoisting with reserved standard lifting lugs for fast crane loading and unloading.
Multiple Heavy-Duty Toggle Quick Clamps: Shorten mold locking and opening cycle with strong clamping force evenly distributed on the mold parting line.
High-Temperature Resistant Anti-Rust Surface Coating: Extends mold service life by withstanding long-term cyclic high-temperature working environments.
Universal Compatibility: Works with all shuttle rotomolding equipment including bi-axial automatic shuttle rotomolding machines and PLC cycle adjustable equipment.
