Our additional services are designed for industries with the highest standards, where precision, quality, and repeatability are crucial.

Additional services Description Individual treatment Serial treatment
HTD Demanding technical products and most series-production products can be heat treated to customer specification only by adopting specially developed heat treatment processes. Standard heat treatment processes do not provide requested properties or properties achieved are not optimal.
HTD service includes development of individual heat treatment process for fulfillment of specifically requested properties. Testing of development heat treatment process is performed on: (1) test parts, (2) for highly demanding parts possibly on a “dummy” furnace load, and (3) on a full production furnace load. Level of testing is agreed with customer before testing starts. Customer confirms results, technology is stored under customer/product ID to assure individual customer treatment.

FIX Heat treatment of demanding serial products is generally made using special fixtures that hold the products in optimal position during treatment. Fixtures enable the products to travel fixed in optimum position throughout the process (to heating, quenching, washing, and tempering), this way assuring required mechanical, microstructural and dimensional properties of products.
Service FIX includes development and fabrication of special fixtures for holding products throughout heat treatment process. Customer shall decide upon development and fabrication of individual fixtures based on technical presentation of benefits achieved in heat treatment using the fixtures.
FIX is offered at price calculated as a sum of: (1) costs of production engineer required for fixture development, (2) costs of fixture materials and fabrication.

WSH Washing of parts in special detergents aqueous-solution before and/or after heat treatment. Washing before heat treatment is performed for cleaning of greasy surfaces or removal of machining or other emulsions to guarantee production stability of heat and surface treatment and highest quality of treated parts. Washing after heat treatment is performed for parts quenched in oil.

✅
WSH ALC Washing of complex parts and parts for nitriding in special alcohol solution before heat treatment. Washing before heat treatment is performed for cleaning of greasy surfaces or removal of machining or other emulsions to guarantee production stability of heat and surface treatment and highest quality of treated parts.

✅
NSP Surface preparation by shot peening. Process of shot peening is hitting the surface with cermic spheres to: (1) clean the surface and prepare it for nitriding treatment, (2) introduce compressive stresses to part surface and with that improve mechanical resistance.

✅

✅
NTP Surface preparation by thermal processes. Correct surface preparation is fundamental for successful nitriding. Special attention must be excersized in preparation of critical parts. NTP process is designed for preparation of special parts before nitriding process.

✅

✅
NCP Surface preparation by chemical/mechanical protection.
Specific surfaces in nitriding are protected, where for certain reason hard surface is not allowed or brittlenes is prevented. Example are sharp edges, threads, surfaces for subsequent machining or other.

✅

✅
LAB Our customers are offered complete laboratory services, starting at individual tests and measurements down to full mechanical and microstructural examination of materials, reporting and certification, all according to ISO 9001 and  IATF16949.
Laboratory services (as for example: microstructural analysis, hardness profile, chemical analysis, fracture analysis, various mechanical tests, measurement of surface-impurity contents, etc) are specified in laboratory.

✅
PPAP Production of series parts with highest quality standards requires preparation of documentation for exact process definition. Documentation includes exact guidance to testing, introduction and execution of production process including flow charts, risk analysis for non conformities and possibilities to reduce risk and errors. Production process is defined in detail, including equipment utilized, process supervision and guidance to quality assurance, packing and shipment.
Our customers are offered complete preparation of APQP and PPAP procedure and execution of heat treatment process in compliance. Processes are generally used for production of parts for automotive industry.
Procedure development and execution is offered at price based on actual costs of QA engineer and laboratory services utilized.

✅
SPC Measurements of dimensional and other key properties on products in series production are generally performed on statistically representing sample. Based on statistical evaluation of measurement results one is capable to predict deviation of measured parameters on entire production.
Our customers are offered statistic evaluation of parameters measured in our laboratory to achieve high production stability and reliability.
SPC service is offered at price based on actual costs of QA engineer and laboratory services utilized.

✅
DIM 3D Service is DIM executed on advanced 3D measurement equipment. The equipment can be programmed according to specific customer requests for preparation of comprehensive measurements protocols of geometrically complex products both before and/or after heat treatment.
Offer for DIM 3D service is made based special customer’s request and evaluation of technical requirements.

✅

✅
COR Products made of low-alloy steel are not resistant to corrosion. They shall receive corrosion protection treatment after heat treatment, especially in case of longer transportation or when they are kept in stock.
Customer is offered technically verified corrosion protection treatments, COR service.
COR service is offered at price defined in general price list.

✅

✅
PAC Customer is offered special packing service executed based on customer’s request. Service PAC is useful in case of sensitive products, high-series products, direct shipments to destinations with specific packing pr product-protection requests.
