The brake pad compression column vulcanizing machine is a specialized equipment designed for the hot pressing process of brake pads for automobiles, motorcycles, and various transportation vehicles. This model adopts a four column guiding structure, with a pressing form of downward pressure (plunger rising to close the mold, falling to open the mold). The whole machine consists of three parts: the main engine, hydraulic system, and electronic control system. The structure is compact, the operation is convenient, and it is safe and reliable.
The equipment is widely used in the compression molding production of friction material products such as disc brake pads and drum brake pads, and is suitable for the manufacturing needs of brake pads in passenger cars, commercial vehicles, new energy vehicles, and rail transit.
Equipment structural characteristics
✅ Four column guidance, smooth operation
Adopting a four column frame structure, the upper crossbeam, lower crossbeam, and columns form a stable load-bearing frame. The column is threaded through the positioning hole of the upper crossbeam through a guide sleeve, and the mold closing oil cylinder drives the upper crossbeam to rise and fall vertically along the column. The guide sleeve ensures a smooth and accurate opening and closing process of the mold, with high repeat positioning accuracy.
✅ Downward pressure design, easy to operate
Unlike traditional upward pressure vulcanizing machines, downward pressure vulcanizing machines use plunger lifting to achieve mold clamping and pressurization, and rely on the weight of the hot plate, platform, and plunger to drive the working fluid to flow back. This design makes the mold installation space more spacious, making it easier for operators to pick up and place workpieces and clean the mold, especially suitable for mass production scenarios such as brake pads.
✅ Locking force system, stable and reliable
This model adopts a locking ring or column rectangular groove locking structure, with a pressure cylinder providing locking force. The upper crossbeam, pressure cylinder, locking device, column, lower crossbeam, and mold form a closed force system, effectively eliminating mold separation displacement caused by component deformation and ensuring the accuracy and density uniformity of brake pad forming.
Core performance advantages
✅ Precise pressure control
Equipped with a servo variable pump and proportional pressure valve, it can achieve stepless adjustment of fast descent, slow pressure, holding pressure, and pressure relief stages. The pressure control accuracy can reach ± 1%, and the position repeatability accuracy is ± 0.05mm, effectively reducing the occurrence of burrs and improving the uniformity of product density.
✅ Intelligent temperature control system
Adopting multi zone independent heating with upper and lower molds, integrated PID self-tuning algorithm, temperature control accuracy can reach ± 2 ℃, and the temperature difference of the hot plate working surface is ≤ 3 ℃. Support multiple programmable heating and insulation curves to ensure sufficient resin curing reaction and prevent burning.
✅ PLC automation control
The whole machine is centrally controlled by a PLC programmable controller, equipped with an industrial touch screen human-machine interface, with sensitive operation, low failure rate, and convenient maintenance. Supports three operation modes: manual, semi-automatic, and automatic, and can achieve two molding processes: fixed pressure and fixed stroke.
Scope of application
✅ Automotive braking system: disc brake pads, drum brake pads for passenger cars/commercial vehicles/new energy vehicles
✅ Motorcycles and electric bicycles: brake pads for various types of motorcycles and electric bicycles
✅ Rail transit: high-speed rail, subway brake pads
✅ Industrial Machinery: Construction Machinery, Mining Machinery Brake Friction Plates
