DESCRIPTION

SPG series fully-automatic powder compacting press

SPG series compacting press is suitable for automatically dry pressing and forming of different powder products in powder metallurgy, fine ceramics, magnetic materials and other relevant industrial application.

Characteristics:
  1. The compacting press adopts the most advanced powder compacting technology from abroad and has been developed, boasts a quality up to international advanced level.
  2. The concave mold will not move while blank is being pressed, and due to the adoption of concurrent pressing method of upper and lower convex molds from two directions, the products pressed is of uniform density and good quality (high acceptance rate).
  3. Adjustment like material filling and pressure increasing can be made during operation.
  4. It is easy to load or unload for the die set.
  5. The forming blank running rate can be infinitely adjusted.
  6. High machining precision, good consistency for the molded blank size and weight.
  7. Demould pressure is reduced. by using core bar floating
  8. All movement of the machinery is conducted by mechanic drive, thus it boasts a high working reliability.

Causes of Premature Wear on Punches and Dies
  1. Improper alignment of the punch and die: Misalignment causes the punch to shear into the die, making it appear naturally worn. If a punch shows wear on one side only, the cause is usually improper alignment.
  2. Excessive stripping force: Insufficent clearance between the punch and die can drastically increase stripping force. Proper clearance results in a stripping force of approximately 20% of punching force. Insufficient clearance can increase stripping up to 30%. Since wear is typically proportional to applied force, proper clearance greatly extends tool life
  3. Nibbling: Nibbling while using a standard punch causes the punch to be thrust sideways and shear into the die. When nibbling or notching, a punch that has a guide heel should be used to avoid sideways thrust.
  4. Hard and/or abrasive materials: Standard punches usually are subject to premature wear on extremely hard or abrasive materials. A better grade of tool steel, such as high-speed steel, should be used if at all possible. Cutting or die lubricant is highly recommended in these applications.
  5. Tapered parts: Punching a tapered part without using dies with a proper bevel will cause excessive wear. For best results and extended tool life, a die that has been beveled to match the taper of the part should be used.
  6. Soft, "gummy" materials: Soft materials such as copper and aluminum tend to gall and stick to the punch. Use of a lubricant will increase the life of the punch and die.
  7. Sharpening punch and die too late: A punch and die should be sharpened when the sharp cutting edge can be restored after grinding. The number of holes punched before sharpening is needed varies greatly with the type and thickness of the material.
