Saf-T-Block Options

• Protective End Caps
  Designed to prevent damage to safety press block that might reduce effective tonnage rating. These caps are strongly recommended on top and bottom.
   
• Wedges (Aluminum or Hardwood)
  Used to fill the gap between the safety press block and the upper slide (RAM). Aluminum is the most durable and much preferred, though hardwood is available.
   
• Handles
  Provides a safe method of handling safety press block. Two handles are highly recommended for longer blocks and heavyweight adjustable models.
   
• Power Cut-Off System
  • In storage When the safety block is stored on the side of the press with the safety plug connected to the control circuit, the press is operative.
  • In use When the safety block is in the press bed area with the safety plug disconnected from the control circuit, the press is inoperative.
  • This system complies with OSHA Energy and CSA lockout regulations.

• Holder
  Safety press block holder provides a safe, designated place near electrical connection. It is available for all our safety press blocks, including any accessories. Rubber retention strap in included.

Correct Block Length is Critical

Maximum .250" of daylight. Under no circumstances should there be more space between the top of the Safety Block and the die, or between the top of the Safety Block and the slide or platen if the die is absent. It is absolutely critical to accurately calculate the needed length. An opening greater than .250" changes the force of a moving slide from static to dynamic.

The Advantages of Aluminum

Many materials are available for use in blocking the ram and upper die of a press. However, 6061-T6 or T651 aluminum offers much higher extruded strength per cubic inch of material than other known press safety block materials on the market such as magnesium.

When static load capacity of material is compared, aluminum becomes the clear choice.

Use only certified material. Aluminum is malleable, and will deform. Magnesium is supposed to fracture at a 45 degree angle, but can fracture and cause shrapnel. Steel should never be considered due to potential shrapnel issues.
