YINGCHUANG Custom Stainless Steel Rotomold Mould, Bi-Axial Rotational Molding Mold For LLDPE Plastic Water Storage Tank Casting Production is customized stainless steel rotational molding mold independently manufactured by YINGCHUANG Rotomold Workshop. This series of molds is specially designed to match all types of bi-axial shuttle, multi-arm and carousel rotational molding machines, dedicated to mass production of 1000L–50000L LLDPE vertical plastic water tanks, horizontal chemical anti-corrosion storage tanks and sewage plastic containers.

The whole mold is made of thickened industrial stainless steel plate with integral laser cutting and seamless argon arc welding. After multiple precision mirror polishing and stress relief heat treatment, the inner cavity has ultra-high smoothness and uniform thermal conductivity. During rotomolding production, it can effectively avoid surface defects such as bubbles, cold spots, pits, scratches and color difference of finished plastic water tanks. The mold structure is optimized according to bi-axial rotary operation logic, with reasonable split demoulding structure, stable clamping during high-speed rotation and no raw material leakage. We provide full one-stop customization service: customers can customize tank volume, overall size, cavity wall thickness, surface texture, inlet/outlet hole position, tank outline and logo engraving according to product drawings. Stainless steel material features excellent rust resistance, acid and alkali corrosion resistance and high temperature resistance, adapting to long-term cyclic heating inside the heating cabin, with low maintenance cost and stable batch production quality. All mold installation dimensions, bracket specifications and supporting accessories can be adjusted to match different brands and models of rotomolding equipment.

1. Full Customization According To Drawings, Cover All Specifications Of Plastic Water Tanks

   Customize molds freely based on customer technical drawings, covering 1000L–50000L vertical, horizontal, round, square and chemical anti-corrosion tanks. Support personalized design of wall thickness, pipe hole position, anti-slip texture, anti-ultraviolet surface and engraved brand logo.

2. Thickened High-Grade Stainless Steel Material, Rust-Proof, Corrosion-Resistant And Long Service Life

   Adopt thickened stainless steel plate as raw material, integral seamless welding, high structural rigidity, not easy to deform under long-term high temperature cycle. Resist rust and chemical medium corrosion, suitable for long-term continuous rotomolding mass production, with thousands of molding cycles service life.

3. Mirror Polished Inner Cavity, Uniform Heat Conduction, Perfect Tank Surface Effect

   Multi-layer precision grinding and mirror polishing eliminate welding lines and burrs inside the mold. Heat distribution is balanced in the heating oven, LLDPE raw materials melt evenly, finished water tanks have smooth surface without flow marks, pits or chromatic aberration.

4. Bi-Axial Rotary Optimized Split Structure, Easy Demoulding And Stable Rotary Clamping

   Structural design perfectly matches bi-axial shuttle and carousel rotomolding equipment. The split demoulding mechanism is easy to open and close, the locking structure is firm, no mold displacement or material leakage occurs during bidirectional high-speed rotation.

5. Balanced Cavity Heat Distribution, Uniform Wall Thickness For Large Water Tanks

   Optimized cavity layout realizes balanced heat absorption in all areas of the mold, solves the common problem of local thin wall of large thick-wall plastic water tanks, and ensures consistent wall thickness of each batch of finished products for stable mass production.

6. Complete Supporting Accessories, Compatible With All Mainstream Rotomolding Machines

   Equipped with customized mold brackets, bi-axial connecting flanges, high-temperature resistant sealing strips, lifting lugs and positioning pins. Adjust installation size according to two-station, multi-arm and single-arm shuttle rotomolding machines, ready to install and use after delivery without secondary modification.
