A flap mould is a metal tool used to manufacture flaps. It is installed on a vulcanization press or injection molding machine, where heat and pressure shape rubber material into a ring-shaped flap.

A traditional compression mould for flaps typically consists of three parts:

• Top plate: Usually rectangular or ring-shaped, with a recess matching the flap profile on its lower side.
• Middle plate (core ring): A critical component; it is a ring that determines the inner shape and diameter of the flap.
• Bottom plate: Corresponds to the top plate, with a ring-shaped groove on its upper side to hold the rubber compound.

The rubber compound is placed into the bottom plate. When the mould is closed and heated under pressure, the rubber flows and fills the cavity, then cures into a ring-shaped flap.

• Dual-compound flap production: By improving the mould structure, the top and bottom plates can press simultaneously, allowing two different rubber compounds to flow in a controlled manner.
• Easy demolding: Modern moulds feature a threaded ejection mechanism at the bottom. After curing, turning the ejector screw pushes the flap smoothly out, saving labor and protecting the product.
• Injection molding process: Offers precise control over temperature (170–190°C), speed, and pressure, resulting in stable dimensions and higher automation.

Specialization includes manufacturing automatic hydraulic integrated vulcanizing molding machines, frames for automatic dual-tire curing machines, and high-quality tire molds:
