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.

Frequently Asked Questions
Can this blower housing mold be fully customized according to my fan shell technical drawings?
Yes, we provide complete drawing OEM customization service. We adjust blower housing outline, cavity size, mounting hole layout, mold wall thickness and square lifting frame dimensions strictly following customer drawings to satisfy different industrial ventilation fan housing production demands.
Will the thick cast steel cavity deform after long-time repeated high-temperature operation inside the oven?
The mold adopts thick high-density cast steel blank, after precision CNC machining and overall high-temperature resistant anti-rust spraying treatment, no deformation or rust oxidation occurs after long-term repeated high-temperature heating cycles.
What are the advantages of square integrated lifting frame and toggle quick clamps?
The square surround steel frame integrates stable support and crane hoisting functions, fix the mold steadily during heating; heavy-duty toggle clamps provide strong clamping force, realize fast opening and closing, greatly improve production efficiency.
