Overview: Manhole Mould

A manhole mould (or mold) is a specialized piece of heavy-duty industrial formwork used to manufacture the concrete components of underground utility access points (manholes). These moulds allow construction teams and manufacturers to cast standardized, structurally sound, and load-bearing manhole pieces.

Product advantages

Strength and Durability: Manhole molds are typically made of high-strength, highly wear-resistant materials, capable of withstanding prolonged use and repeated impacts, ensuring the manhole cover does not deform or break under the pressure of vehicles and pedestrians.

Prevention of Deformation: The design of manhole molds takes into account the potential deformation of the manhole cover due to temperature changes and geological deformation during use, employing reinforcing ribs and other structural designs to ensure the stability and flatness of the manhole cover.

Anti-slip and Anti-crushing: The surface of the manhole cover often requires appropriate texture or protrusions to increase friction, preventing pedestrians or vehicles from slipping on wet or slippery surfaces. Simultaneously, the design of the manhole cover needs to prevent breakage to avoid potential injuries or traffic accidents.

Material Saving and Waste Reduction: Manhole molds are typically produced using mold casting molding. The mold can be made into various shapes and sizes according to design requirements, minimizing the waste of raw materials and energy and increasing the reusability of the mold.

Easy Installation and Maintenance: The design of manhole molds takes into account the ease of installation and maintenance of manhole covers. For example, holes for easy bolt fixing can be incorporated into the mold design, ensuring simple opening and closing of the manhole cover.

Application

Industrial Complexes

Industrial facilities use manholes for access to utility lines, ensuring seamless operations and easy maintenance of critical systems.

Sewage Infrastructure

Manhole systems form an integral part of sewage networks, enabling maintenance and preventing blockages in wastewater pipelines.

Road and Highway Projects

Manholes are installed along roads and highways to manage drainage and provide access to underground utilities, ensuring road safety and longevity.

Urban Drainage Systems

Manholes are vital components of storm water drainage systems, allowing access to underground pipelines and ensuring proper water flow in urban areas.

Types and Manufacturing Processes

Compression Moulds for Composite Manhole Covers

Compression molding is the most widely used process for composite manhole covers. A typical compression manhole cover mould includes:
Upper and lower mould halves
Integrated heating systems for controlled curing
Vent structures to release trapped air
Compression moulds are especially suitable for SMC and BMC materials, offering high productivity and consistent quality.

Concrete and Polymer Concrete Manhole Cover Moulds

Concrete-based manhole cover moulds are designed to withstand:
Repeated vibration and compaction forces
Abrasive materials
Long production cycles
Robust mould structures and wear-resistant materials are essential for extended mould life.

Our Service

Guarantees Perfect On-Site Fit

Laser cutting and CNC bending achieve a assembly tolerance within 0.2mm, ensuring swift, seamless installation of all precast components.

Maximizes Daily Production Output

An optimized internal design with a 2° draft angle cuts demolding time to approximately 3 hours, enabling a steady output of 20-25 high-quality units per day.

Protects Your Long-Term Investment

Constructed from 14-20mm thick Q355 steel with triple-layer corrosion protection, it withstands over 500 casting cycles without compromising accuracy.

Package & Delivery

Package

Standard export package or Custom.

Delivery

By air express, by sea.
