Product Description

Product Overview

This OEM Custom Horizontal Septic Tank Rotomold features a heavy-duty all-carbon steel rotational mold independently manufactured by SUNMORE ROTO. The mold cavity is constructed from thickened industrial carbon steel plate with full penetration seamless welding, equipped with a full-welded surrounding reinforced steel frame and multiple heavy-duty steel quick-release lock buckles.

This horizontal ribbed septic tank rotational mold is specially developed for mass production of buried three-chamber LLDPE sewage purification tanks, widely used in rural toilet renovation, village domestic sewage treatment, scenic decentralized sewage disposal, and villa underground sewage treatment projects.

Full OEM drawing customization service is available. We can adjust tank cavity length, diameter, outer rib layout, internal partition baffle structure, inlet & outlet pipeline holes, and manhole positions strictly according to customers' finished sewage tank drawings. The thick steel cavity features stable and uniform heat absorption performance, ensuring complete outer reinforcing ribs and consistent wall thickness of plastic septic tanks during long-term batch rotomolding production.

Frequently Asked Questions

Can the cavity size, outer ribs and internal three-chamber partition structure of this horizontal septic tank steel mold be customized?

Yes, full OEM drawing customization is supported. We design and process the steel mold strictly according to your finished septic tank drawings, adjusting cavity dimension, rib layout, baffle and pipeline hole positions as required.

What is the advantage of surrounding integral full-welded steel frame compared with ordinary simple frame?

The surrounding closed steel frame bears rotary force evenly during rotomolding operation, avoids local stress concentration, and provides superior anti-deformation performance for long-term continuous mass production of large horizontal septic tanks.

Is this horizontal septic tank mold compatible with mainstream rotomolding machines?

Standard connecting flanges and integral lifting lugs are reserved on the steel frame, making it compatible with swing arm, shuttle, and carousel rotomolding machines of most brands without extra reconstruction.

Our company supports the national cross-basin water transfer project of Brazil with large plastic storage tanks. Custom ultra-large rotational molds greatly improve production efficiency compared with old split iron molds. Wall thickness of finished tanks is uniform, the reject rate is cut down obviously, which helps us smoothly finish government order delivery.

We bought multiple sets of 0.6T high load bearing rotomold for farm centralized water tank production across Midwest agricultural areas. The mold structural design enhances load resistance during rotomolding, finished small water tanks have uniform wall thickness and strong compression resistance, perfectly matching farm outdoor buried water supply layout. Stable continuous production helps us deliver bulk orders for local agricultural cooperatives.

Our company focuses on offshore small fishing vessels made from LLDPE, we customized exclusive rotomold via their custom boat design service. The technical team provides 3D drawing confirmation before mold production, all design revisions are free within agreed scope. Test boats pass Australia marine safety inspection successfully, production cost is controlled reasonably compared with local mold makers. Long-term cooperation contract is under negotiation now.
