Yumao Steel Rotomolding Mold for Water Tower

Custom rotomolding molds for plastic round tubs and vertical water towers, covering 50L to 5000L capacities. Made of high-grade carbon steel/stainless steel with 2.5–3mm uniform wall thickness, CNC machined for high precision and smooth surface. Ensures seamless, leak-proof, and durable plastic tanks with consistent wall thickness and easy demolding. Compatible with LLDPE/HDPE materials and all types of rotomolding machines. Custom sizes, capacities, thread ports, and rib designs available. Ideal for residential water storage, industrial liquid containment, and water treatment applications. Robust structure, high temperature resistance, long service life, perfect for mass production of high-quality plastic water towers.

The main technical parameters include standard capacity 50L–5000L, mold material high-carbon steel, surface mirror polishing treatment, overall welded structure, easy demolding design and long service life. This rotomolding mold is widely used in civilian domestic water storage, factory industrial liquid storage, aquaculture water storage, environmental water treatment, sewage storage and agricultural irrigation water tank production. It is compatible with LLDPE, HDPE and other common rotomolding raw materials, and fits most mainstream rotomolding machine models on the market.

Product Advantages

This product has obvious advantages of factory direct sales, fine workmanship, reasonable structure and cost performance. With integrated forming technology, the produced plastic water tower has no seam, uniform wall thickness, strong pressure resistance and good leak-proof performance. The mold has high hardness, high temperature resistance and oxidation resistance, which can effectively reduce production failure rate and improve production efficiency. Its core function is one-time rotational molding forming, easy demolding, reusable molding, and it can be repeatedly used for mass production of plastic water tower products.
