Deceleration and Vibration Isolation

40 Jahre Erfahrung 40 years of experience Kunden in 75 Ländern Customers in 75 countries PRODUCTS FOR YOUR SUCCESS As a specialist in innovative deceleration and vibration isolation technology, we develop and manufacture produtcts for machinery and plant engineering. Our success is based on the development of modifications and customised solutions, backed by over 40 years experience and an in-house production facility. Shock Absorbers Heavy-Duty Shock Absorbers Deceleration Cylinders Speed Controls Rotary Dampers Gas Springs Pallet Stoppers Vibration Isolation

PRODUCTION In a production space of 4000 m² (43055 sf), highly automated CNC machines manufacture our deceleration and vibration isolation components. With a real net output ratio of over 90% and highly reliable processes, we achieve rapid and dependable product availability. From the prototype to series production, take advantage of our many years of experience. INNOVATIONS Our engineers are continuously pushing developments in our deceleration and vibration isolation components. Patents, e.g. for Mega-Line industrial shock absorbers with high energy absorption, shock absorbers with...

QUALITY Comprehensive in-process inspections during the production and assembly guarantee the high quality of our products. The final inspection is performed on computer-controlled test systems, which can record forces of up to 2 million newtons, and which amongst other things calculate and allow comparison of the precise deceleration curves. Various test methods are used to check our deceleration and vibration isolation components in relation to temperature (-70 to +180°C), corrosion (salt spray), leakage and service life. SPECIAL SOLUTIONS A broad standard product portfolio makes us a...

Benefits Stop Cap AP / AP2 Stop cap with steel core and PU cap (AP) • 40% noise reduction • Increased protection of the impact surface Steel cap with steel core and PUM cap fiberglass-reinforced (AP2) • Longer life time compared to stop cap AP and plastic cap A Integrated end-stop Pro Surf • Improved surface protection against corrosion • QPQ Coating, specialized type of carbonitriding case hardening (carbonitriding, polishing, post-oxidizing) Enlarged Piston hardened, aluminium-titanium-nitride coated High energy absorption and extended life time Salt spray test Sprühdauer in h / Spray...

Noise reducing stop cap with a high security steel-fixing ring Pro Adjust Integrated end stop Protected Adjustment (patented) Hardened, aluminium-titanium-nitride coated Machined flats for spanner Helix Principle + 300% Energy / - 50% Costs Pressure Tube Adjustable one-piece nitrite hardened pressure tube, that fits closely to the housing thus giving good guidance ProTec Solid base without retaining ring www.weforma.com | Made in Germany

Selection Five basic criteria are required for sizing the shock absorbers 1. Formulae EFFECTIVE MASS Additional external forces acting on the mass e.g. propelling force F (N) Number of strokes of the shock absorber per hour X (1/h) (At 1/h: number of strokes per year) Number of parallel shock absorbers In individual cases, other additional information may be required. * Calculation for optimum setting. Allow a safety margin! For a utilizaltion per stroke >80 % the approval of Weforma is necessary! Kinetic energy Propelling force Drive power Propelling force energy Pneumatic drive force...
