CERTIFICATION
- The Quality Management System is in accordance with ISO 9001:2009.
- We successfully completed the recertification in June 2015.
- Continuous improvement of quality and searching for the most optimal production technologies together with the customer is considered to be a continual process.
- Reduction of possible defect occurrence and thus reduction of additional costs for our customers and our plant is considered to be a priority and a condition for the successful handling of current and future competition.
- Since 2001, when the plants where purchased by their current owner, the quality has markedly improved.
QUALITY CONTROL
The foundry is fully equipped for performance of continuous quality assurance check:
- testing of chemical composition using device for spectral analysis SPECTROLAB
- mechanical testing of tensile strength
- testing of hardness according to BRINELL
- metalographic tests of material structure
- laboratory testing of shaping sands
- and also arrangement of other specialised certifications, including X-ray testing
THE PRODUCTS ARE DELIVERED WITH
- certificate, it means report about internal testing of material and dimensions for customer orders
- declaration of conformity to specifications - verifications of surfaces, shapes and foundry defects on a fixed number of castings from each batch
Bronze
Production technology:
Sand casting technology uses two means of shaping, manual and mechanical. Manual shaping is suited for castings of greater dimensions, higher weights and for more complicated castings. Mechanical shaping guarantees higher labour productivity, casting precision and also stable conditions during production. We are producing also centrifugal castings of cylindrical shapes of bronze and brass alloys for production of bushes, slide bearings and further cylindrical components within small and middle-size series.
Usage:
Machinery parts with friction stress at high pressures, dynamical loading, partially corrosion resistant: gear wheel rims, bearing cases with flanges, pump bodies, artistic objects (bells, doorhandles, plagues etc.).
Aluminium
Production technology:
Sand casting - sand casting technology uses two means of shaping, manual and mechanical. Manual shaping is suited for castings of greater dimensions, higher weights and for more complicated castings. Mechanical shaping on the other hand guarantees higher labour productivity, casting precision and also stable conditions during production.
Usage:
E.G.: flanges, transmission cases, belt holders, fan parts, manual wheels, covers and artistic castings (lattices, plaques, benches, pedestals etc.).
Machining
Both plants have their own MACHINE SHOPS, which are equipped with standard and 5 CNC machines, including needed technological devices. If our own capacity is not able to meet customers' demand, machining is provided in cooperation with long-term partners. Currently a project of machine shops enlargement has been prepared, in case our stable customer needed us to have larger machining capacity.
Patterns
In our plants, there is a long-term tradition of moulds and patterns production and of possible adjustment of equipment delivered by our vendors and their continuous maintenance and repairs. Production of patterns is done on the basis of drawings with routings provided by customer and also trough our own designs.
PATTERN SHOP KRNOV is equipped for the production of simple wooden patterns and continuous repairs of patterns, casting of patterns and cores from resins and following treatment and fitting on forming plate.
OUR TOOLING SHOP mostly covers the needs of production and repairs of pattrns and moulds. If we are not able to fully meet the customers' demand, for capacity or technology reasons, or if it is for customer preferable (e.g. when delivery date ASAP, or maximal tooling quality, minimal tooling costs with regard to product life time etc. is required), we provide the tooling production in cooperation with reputable specialised tooling shops we have good experiences with.
