Frequently Asked Questions

Can the septic tank's outer shape, internal partitions and manhole positions be customized on this steel mold?

Yes, full OEM customization service is available. We design and manufacture the mold strictly according to your finished septic tank drawings, including adjusting outer contour, internal separation baffles, external rib layout, manhole size and reserved sewage inlet/outlet hole positions.

Will this thick steel septic tank mold deform after thousands of high-temperature rotomolding cycles?

The mold cavity is made of thick carbon steel with full penetration welding, plus surrounding heavy reinforced steel frame. The integral rigidity is extremely high, keeping stable shape without bulging or deformation after long-term repeated high-temperature rotation.

Is this septic tank rotational mold compatible with mainstream rotomolding equipment?

Standard connecting flanges and lifting lugs are reserved on the mold frame, which can be matched with most domestic and foreign swing arm, shuttle and carousel rotomolding machines without extra modification.

We have cooperated with this supplier for two batches of fuel tank molds. Made of thickened steel, the mould is wear-resistant and durable for long-time continuous mass production. After-sale engineers offer remote debugging guidance when we test production.

We purchased multiple sets of infrastructure-grade rotomolding molds for municipal engineering centralized water supply projects. The aluminum mold has even heat distribution, finished large water tanks feature uniform wall thickness without shrinkage or deformation. It can cope with continuous mass production for government bidding projects, and we intend to place additional orders for new urban infrastructure construction.

Our factory provides supporting tanks for mountain area dynamic water supply and mountain farm pumping water storage system. PT6000 6T high load mold matches our LLDPE raw material perfectly. Excellent structural rigidity reduces mold deflection during high-speed rotomolding, defective rate of dynamic water tanks drops significantly.
