Product Description

We are holding rich experience in the domain of offering Industrial Beryllium Copper. It is recognized as excellent mold alloys for the plastic industry as injection molds and tooling for blow molds. It is used to produce superior quality plastic parts with minimum total production costs over other competing mold materials. This is due to its optimum combination of hardness, wear resistance, thermal fatigue, and thermal conductivity. Industrial Beryllium Copper is available in different specifications for clients. 

Features:

  • Higher conductivity
  • Lower hardness
  • Resistant to breakage 

BERYLLIUM COPPER IN PLASTIC MOULD INDUSTRY


NGK PLUS and ULTRA Performance Attributes
 
NGK PLUS and ULTRA Products are recognized as excellent mold alloys for the plastic industry as injection molds and tooling for blow molds. They are known to produce superior quality plastic parts with minimum total production costs over other competing mold materials. This is due to its optimum combination of hardness, wear resistance, thermal fatigue, and thermal conductivity. Plate products are available in three grades from two alloy systems: PLUS is a higher conductivity, lower hardness beryllium copper alloy. ULTRA is a lower conductivity, higher hardness beryllium copper alloy.

Typical Applications
 
PLUS
ULTRA
  • Low pressure blow molds
  • Limited applications for injection molds
  • Inserts in steel & aluminium molds for higher
    cooling rates at critical areas
  • Sealing tools
  • Cooling inserts
  • Plungers for die casting of light metals
  • Nozzles & needles for hot runner systems
  • Injection molds & high pressure blow molds
  • Inserts in steel molds for higher cooling
    rates at critical areas
  • Inserts in aluminium molds for higher
    strength & wear resistance
  • Cooling inserts
  • Nozzles & needles for hot runner systems
 
 
Performance
 
PLUS

ULTRA
  • Moderate in strength
  • Provides the best
    conductivity of all materials
  • Higher in strength than
    aluminium
  • Can be used as a total mold
    system or as an insert in other
    molds

  • Higher hardness Recommended where greater
    resistance and higher operating
    pressures are required
  • Can be used as a total mold
    system or as an insert in other
    molds

Working Temperatures of PLUS and ULTRA Plate and Plastic Processing Temperatures
 
 
 
Beryllium Copper, with its high thermal conductivity compared to steel, offers significant advantages in minimizing part distortion, dimensional control and cycle time. Its superior thermal fatigue and strength characteristics allow longer tool life and less down-time. All of these advantages translate into higher productivity and cost effectiveness.

NGK Rod and Plate provides exellent resistance to the corrosive by products of molding operations such as hydrochloric acid. This property make PLUS and ULTRA Plate the mold material of choice for PVC and other corrosive resins.

Filled resins have a higher than normal tendency to wear mold materials. PLUS AND ULTRA Plate competes favorably with most steel in wear applications and it can be plated with nickel and chromium to further enhance performance.

The high strength and wear resistance of NGK, ULTRA Plate provides superior performance at neck and thread areas, as well as bottoms, when combined with other mold materials.

Welding Repair
 

Beryllium copper inserts and molds can be joined and or repaired by resistance welding, TIG and MIG welding. However, precautions must be taken against softening and oxidation of the material. Filler metal of the same alloy should be used and oxides, oil and dust should be removed from the parts prior to welding.
