Aluminum mould blocks are one part of a double-wall corrugated pipe forming system. Their design should match the pipe profile, mould circulation, cooling method, changeover plan and maintenance requirements. Mould material alone does not establish the line’s diameter range, production rate or finished-pipe performance.
RUNNING MACHINE starts with the structured-wall pipe drawing and required product checks, then discusses extrusion, forming, cooling, cutting, handling and tooling as one project.
Define the pipe and tooling requirement
- Resin and formulation
- Inside and outside diameter range
- Corrugation geometry and wall structure
- Required stiffness or other product classification
- Socket, joint and end design
- Mould-block sets and planned size changes
- Cooling-water conditions
- Pipe cutting and handling method
- Applicable product and test requirements
Typical equipment scope
A project may include material feeding, extrusion units, die head and calibration tooling, a double-wall corrugator, aluminum mould blocks, cooling circuits, cutting, support and stacking equipment, control integration and selected auxiliaries. The final scope depends on the pipe range and factory conditions.
Questions to ask about mould blocks
Confirm the mould-block material and construction, quantity per size, cooling passages, surface and dimensional inspection, identification method, change parts, storage, cleaning and replacement process. Ask how the mould design corresponds to the agreed pipe profile and acceptance sample.
Information needed for a proposal
- Pipe standard, drawing and reference sample
- Resin and formulation information
- Size, wall and stiffness range
- Corrugation and smooth inner-wall requirements
- Socket or joint details
- Priority tooling sets and changeover sequence
- Target output with test basis
- Cooling-water supply and return conditions
- Cutting, support, handling and stacking plan
- Factory power, air, water and floor-space information
Frequently asked questions
Does an aluminum mould determine production speed?
No. Output depends on the complete process, including extrusion, forming, heat removal, pipe profile and downstream handling. Compare proposals using an agreed trial condition.
Should spare mould blocks be included?
Discuss critical spares, wear inspection and replacement planning for the intended product schedule. The quotation should distinguish production sets from spare parts.
How should the formed pipe be accepted?
Use the agreed material and tooling, record stable settings, measure the wall and profile, check the inner surface and complete the specified product tests.
