Casting characteristics

Proton-PM has some modern equipment that makes it possible to

  1. Produce sand cores made with the help of Laempe-supplied equipment using the Cold-Box-Amin process;
  2. Provide full product cycle for cast sections:
    • prepare auxiliary materials;
    • make wax samples using a range of compounds;
    • make ceramic moulds using ethyl silicate;
    • deal in mould-baking and air- and vacuum-based mould casting;
    • clean up the gating system;
    • deal in thermal treatment of castings in an automated furnace made by IPSEN (Germany);
    • deal in mould-etching.
  3. Carry out a range of casting quality control procedures:
    • visual control;
    • luminescent control;
    • X-ray control;
    • color flaw detection;
    • controlling the chemical composition of the product;
    • controlling the mechanical properties of the product.

Electroplating and chemical treatment of products

The company owns twenty production lines meant for coating and chemical treatment. These lines are suitable for:carbon steels; heatproof and heat-resistant kinds of steel; nickel alloys;titanium alloys; copper alloys; other types of materials.

  • carbon steels;
  • heatproof and heat-resistant kinds of steel;
  • nickel alloys;
  • titanium alloys;
  • copper alloys;
  • other types of materials;

Coating characteristics

The quality of surface coating is estimated based on the following criteria:

  • thickness of coating ( method, metallographic method);
  • adherence of coating quality (heating method, scratch brushing, mesh spacing in scratches);
  • corrosion resistance and sponginess;
  • outward appearance.

Pressure processing of metals

Proton-PM’s equipment can be divided into three groups, based on the standard size of processed parts and the kind of operations needed:

  • Equipment meant for treatment of parts up to Ø100 mm;
  • Equipment meant for treatment of parts ranging from Ø 100 mm to Ø 400 mm;
  • Equipment meant for treatment of parts Ø 400 mm and up.

The enterprise has 59 pieces of pressure equipment with press power ranging from 10 tons to 1,600 tons, the 1,600-ton hydraulic press used for making large sheet-metal stamping being the most unique in terms of its capacity.

Thermal treatment

Thermal treatment can be applied to both half-finished products made from steel and alloys (castings, forgings, rolled metal, etc.) and ready-made assembly units and parts. 

Thermal treatment

  • baking;
  • normalization;
  • heat hardening;
  • drawing;
  • aging treatment;
  • subzero treatment.

Thermal treatment can be applied to both half-finished products made from steel and alloys (castings, forgings, rolled metal, etc.) and ready-made assembly units and parts. 

Thermal treatment

Equipment used for thermal treatment:

  • heat-treatment furnaces (electric furnaces with air fields or vacuum furnaces);
  • tanks (electric tanks with saline or alkaline liquid);
  • specially designed muffles and containers can be used for thermal treatment of ready-made parts and assembly units in vacuum, argon, or nitrogen).

Cooling substance: air supplied still or through blow-off. Small steel or alloy billets can be given thermal treatment with water cooling (using water tanks 1,100 1,140 1,000 mm). Saline and alkaline baths can be used for non-oxidation thermal treatment of particularly important parts (e.g. springs).

Maximum furnace dimensions: 2,500 mm, depth: 3,500 mm (depending on the purpose the furnace is used for). Maximum working temperature: up to 1,2000 (up to 100 imprecision is allowed, depending on the maximum working temperature used). 

Vacuum drying of parts and assembly units with heating

Maximum dimensions of furnace body: 2,500 mm, depth: 3,500 mm (depending on the purpose the furnace is used for). 

Vacuum drying of parts and assembly units with heating

Maximum dimensions of furnace body: 2,500 mm, depth: 3,500 mm (depending on the purpose the furnace is used for).

Maximum working temperature: up to 350 (up to 250 imprecision is allowed, depending on the maximum working temperature used).

The insides of the processed parts can be given inert-gas flushing for better oxidation protection. 

Nondestructive control methods
