Shot Blasting Workhouses

This workshop is equipped with 6 shot blasting machines for cleaning and de-scaling heat-treated components. It consists of two main lines:

A : Gantry Shot Blasters

    • Large Overhead Shot Blaster (WMKD):

      • Maximum load per hanger: 2 tons
      • Maximum part dimensions: 20.3m x 8.1m
      • Hanger speed: 14 meters per minute This Swiss-made machine is primarily used for shot blasting front-end components such as axles, camshafts, crankshafts, and others with dimensions up to 20.3m x 10.3m x 8.2m. This machine is particularly suitable for long components. The machine has 3 hangers for shot blasting parts, each with a capacity of 2 tons. Parts are loaded onto the hangers, with a wide range of dimensions and weights up to 1600mm x 1900mm and 2 tons.
  1. Small Overhead Shot Blaster
This machine, similar to the large overhead shot blaster, is used for shot blasting long components. It has 3 hangers with a capacity of 500 kg each and can accommodate parts up to 2200mm x 1600mm. Both the large and small overhead shot blasters are primarily used for shot blasting automotive front-end components such as crankshafts, camshafts, and axles, which due to their length, are susceptible to bending when shot blasted in a hanging position.

B. Rotary Conveyor Shot Blasters

  1. Large Shot Blaster 1 (WST): This Swiss-made machine is used for shot blasting and de-scaling various components with a weight capacity of 800 to 1200 kg per batch, depending on the part type and geometry. In this machine, parts are loaded into the shot blasting chamber by the machine’s loader and are rotated slowly by a conveyor while being shot blasted to ensure that all surfaces are cleaned and a smooth finish is achieved. The maximum load capacity of this machine is 2000 kg.
  2. Large Shot Blasters 2, 3, and 26GN: These machines, manufactured in England, are used for shot blasting various heat-treated components, similar to the large shot blaster 1. They have a capacity of 800 to 1200 kg per batch. These machines also have internal conveyors for rotating the parts.
  3. Small Shot Blaster: 15GN
This British-made machine operates similarly to the larger shot blasters. Its capacity ranges from 350 to 1223 kg, depending on the part, and is primarily used for shot blasting very small components.

Cold Coin Pressing Line

This line consists of 5-coin presses used for cold coining parts such as various connecting rods, triangular parts, and fork ends that require press quenching. The combined capacity of these coin presses is approximately 12,000 to 15,000 parts per day.

:1000-Ton Press (Iran Press Hydraulic Press)  This press, manufactured by Iran Press, is used for coining various parts, including Peugeot triangular parts. Its capacity is 150 to 300 parts per hour.
750-Ton Coin Presses 1 and 2: These British-made machines are used for press quenching various parts such as connecting rod cups and washers. The capacity of these machines, depending on the part type, ranges from 250 to 400 parts per hour. The table dimensions are 610mm x 610mm.
1500-Ton Press: This TRHD brand press is used for coining large connecting rods. Its capacity is similar to the 1000-ton press, ranging from 150 to 300 parts per hour depending on the part.
2000-Ton Press: This Russian-made press is used for coining parts. It operates similarly to the 1000-ton press and has a capacity of 200 to 300 parts per hour.
