1 . company with a tradition of more than 70 years. DESIGN CHECKING PATTERN SHOP TOOL SHOP

2 FIRM The history of the carpentry firm begins in the years of World War II. At first, three to eight employees were employed in the firm. After World War II, two sons were forced to join the Pujman firm in Nove Ransko. Here, with the arrival of modellers from Stare Ransko and the arrival of carpenters from small firms in the surroundings, there was mutual sharing of experience. Oldrich Novak Sr. worked in the pattern shop in Nove Ransko until his retirement. His son Oldrich Novak worked there as the pattern shop head and mould designer until In the same year, he founded his own company, which dealt with model equipment and mould production. Gradually, he employed from two to 15 employees.production started in his father s shop; in 1995, he built a new pattern shop plant and gradually added a further two extensions to give it the current form. Gradually, introduction of CAD/CAM technologies, CNC machining, 3D measuring, and division of the plant into the pattern shop and the tool shop took place. DESIGN In 2010, he handed the firm over to his son - the current owner. Now the firm employs 30 employees, of which 8 are designers and 18 are production employees. Currently, 30% of production is pattern equipment for foundries and 70% of production is checking jigs for the automotive industry (40% in the domestic market, 60% abroad (Slovakia, Germany, Poland, England, Italy, France, Spain, Portugal, USA). We supply products especially to multinational firms focused on automotive industry. Annually, we produce approximately 800 jigs. The highest percentage is formed by checking jigs for all distributions of fluid systems in cars and jigs for checking external plastic parts of the exterior or sheet metal pressings. We offer: Creation of 3D checking jigs for plastic, metallic, and sheet metal products of various industries Creation of 3D foundry models, prototypes, jigs, and moulds Modification of 3D data of foundry models, programming of CNC milling Company software: CAD workplace (Surfcam, SolidWorks, ProEngineer, Catia) CAM workplace (SUFCAM, HSMWorks) Data communication: 2D:.dwg,.dxf 3D:.iges,.step

3 TOOL SHOP Production of checking jigs, moulds, chill moulds, engineering part machining. The main programme is the production of checking jigs for: Plastic, metallic, sheet metal parts of various industries (mostly automotive) Pipes and hoses of all fluid distribution systems We supply jigs according to the customer s specification or according to our own design with regard to the checking and tolerance of parts. Possible to supply in various variants: Manually controlled With electronic signalling of accuracy using sensors and detectors and pneumatic faste ning of parts Combination of the aforementioned variants The supply of a 3D measuring protocol for each jig produced is automatic. Machinery: 3xCNC-Hurco, 2xNC-FKH 80, 4xNC milling cutter FNGJ, lathes

4 PATTERN SHOP We produce: Wooden checking jigs of pipes and hoses of fluid distribution systems Wooden models and cores for piece, serial production, and foundry production Wooden, metallic model boards for manual or machine forming Models from casting resins Models from polystyrene for piece casting Repairs and design changes of existing models according to the technology of various foundries Moulds for laminating Moulds for heat plastic shaping

5 CHECKING We check the accuracy of products using a 3D arm (the PowerInspect program). We measure both smaller parts within the arm scope (2.4 m) and large models, jigs Thus, we obtain both the product dimension data and e.g. the shape and position deviation data or the evaluation in comparison with the CAD model. The inspection output is the measuring protocol, which is always a part of the supply of our products. CASTINGS In co-operation with Czech foundries we ensure production or technological assistance in introducing the castings of the following materials and sizes into production: Aluminium, brass and bronze alloys: machine and hand moulded 0.2 1,600 kg as per CSN cast into metal moulds kg Grey cast iron: GG 15, GG 20, GG 25 machine-moulded 0,5 100 kg hand-moulded kg Malleable cast iron: GTW 35-04, GTW 40-05, GTWS-38, GTS-35 machine-moulded 0,03 7 kg Ductile cast iron: GGG 40, GGG 50, GGG 60 machine-moulded 0,5 10 kg hand-moulded kg Cast steel: per ISO, ASTM, DIN, BS standards machine and hand-moulded
