The brake  shoe carries the brake block. The block was usually made of cast iron or composition material. when the brake is applied, the shoe moves and presses the block against the thread of the wheel. This scrubbing causes wear and tear on the wheel tread and often causes brake squeal. Tread brakes on passenger trains have now largely been superseded by disc brakes.Locomotive brake shoes are available in both composition and cast iron material according to AAR M-926. Various sizes are available to suit your locomotive application.Our brake shoe design and manufacturing material help mitigate broken steel backs, friction material delamination and metal pickup, leading to fewer premature brake shoe removals.

BMC Special Injection Molding Machine

AOTAI Servo Driving System

1. Show High Precision:The accurate injection positioning,pressure, speed ang pressure maintaining, to ensure the ensure the repeatability error of injection accuracy less than 0.3%to achieve precision molding.

2. Super Energy-Saving Features:Compared with standard injection machine, the energy saving rate can reach 40%-70% for the same plastic production.

3. High Efficiency:Compated with standard machine,the total efficiency can increase by 10% and dragging capacity is can increase by 18%

4. High Respomse System:The system acceleration and deceleration performance is quite agile and force &speed regulation is very sensitive. The sampling processing speed can reach 100KHZ and system quick start time can reach 0.05s.

5. Maintain Stability and Reliability:The pressure or speed is stable and switch of pressure maintaining is smooth and accurate.

6. Low Oil Temperature:Avoid high pressure unloading and low oil temperature situation during operation. Improve the operation performance,promote using efficiency and save a large quantity of coolong water.

BMC Injection Molding Machine is equipped with thermosetting physicochemical components which is specialized for BMC material. and it has sysytem optimization module which is composed of specific charging high torque hydraulic motor for charging and special injection hudraulic cylinder etc.

J system characteristic

Design and reseatch on high energy-saving injection molding machine has been regarder as our National Torch Plan and we are the earliest company who is engaged in this project. Servo motor can disctate different machine action according to product workmanship requirement. To inqut data into the controller and instruct different workload demand of every machine action quickly. The linearity of servo driving system operational process keeps good tracking with workmanship instrucion. In this case, the system pressure and flow becomes a closed loop, which achieves high machine performance & high energy-saving by 40%-70%. With this high-response system, the efficency of machine can be more than 98%.
