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.
