Automotive Components

Engine Valve Springs
Mubea valve springs are cold-formed wire springs made of pure spring steel with the highest tensile strength. These highly stressed springs ensuring reliable valve closure with an optimum spring force. Each engine valve springs and auto coil springs is CNC coiled, stress relieved, ground, shot-peened and heat set.

Features

• Prevents lifting of the cam contour at high engine speeds
• Exceptionally low force tolerances and relaxation behavior
• Extremely high fatigue strength
• Cylindrical springs with symmetrical or asymmetrical coiling
• Conical or beehive valve springs are also available

Spring Band Clamps
Constant tension spring band clamps are self-locking fastening components. These spring band clamps securely seal hose connections, influenced by vibrations under fluctuating pressure conditions. Spring band clamps are suitable for cooling-heating circulation systems, fuel line systems, servo return systems, shock absorber connections, etc.

Features

• Works efficiently under temperature range of –40°C to +200°C
• Made using Chrome vanadium alloy spring steel 51CrV4
• Available in widths of 8.4, 10, 12, 15 and 20 mm
• Nominal diameters range between 10 and 90 mm
• Can be used in the most varied technical systems connected by hoses
• Available in different models including Space saving, pre-opened and pre-positioned variants
• Multilayered, chrome VI free coating provide option for different colors

Suspension Coil Spring
Suspension coil springs are produced in a cold state, using spring wire with highest tensile strength. The cold forming process imparts high flexibility in the spring design. Thus allowing for adaptation of the geometry to any suspension strut or axle cinematics without making it necessary to use special dies. In addition to cylindrical springs, lateral force compensating side load (SL) springs are also produced.

Features

• Patented design (SL) that ensures increased driving comfort, safety and optimum use of space
• Made using quality wire rods and newly developed High Performance Material (HPM) steel
• The coil spring is tempered surface to achieve a high tensile strength
• Available in different specifications based on the requirement of the customers

Stabilizer Bars
The range of suspension stabilizer bars includes tubular stabilizer bars (outer diameter - 17 to 40 mm) and solid stabilizer bars (outer diameter - 12 to 33 mm). In addition, all add-on parts are also produced like rubber bushings, clamps, links, etc. Tubular stabilizer bars are provided with a weight reduction of up to 50% as compared to other bars.

Features

• Special provision for additional weight reduction
• Optimally designed for strength based on the load using variable cross-sections
• Vehicle stabilizer bars are shaped through cold-form process to maintain the material properties required for high fatigue strength
• CNC cold bend-tubular with resistance heated and quench temper

Belt Tensioner System
Automatic belt tensioner systems are offered for all FEAD (front end accessory drive) belt drives. This includes solutions for restrictive mounting space requirements, including weight and cost-effectiveness. Cutting-edge modular assembly systems like rotary index tables are used for the production. This ensure highest product quality and economy.

Features

• Automatically maintains correct accessory belt tension
• Maintains its correct alignment
• Automatically dampens normal accessory system vibrations
• Eliminates need to adjust / re-tension
• The unique design prevents slip (noise / excessive belt wear)

Head Rest
Headrest retaining rods and supports are produced in automated production lines. Tools are primarily designed in-house to ensure timeliness and cost-effectiveness. Pre-rolling and milling the rods allow for high-precision notch designs. Thin walled tubes can now be used, thanks to the introduction of this technology into production.

Features

• Reduced weight for better support and increased comfort
• Made using simple construction and high tensile dual steels
• Resistant to rust and corrosion
• In addition to hard chrome plating, Zinc plating or cathodic dip painting are also provided
• Can be customized as per the client's demand or requirement

Tailor Rolled Products
Tailor rolled products (TRP)® are produced using a cold rolling process developed by Mubea known as flexible rolling. The cold-rolled strips provide variable sheet thicknesses in the direction of rolling. The process chain for producing TRP includes adapted heat and surface refining processes and downstream classic cold-forming processes.

Features

• Tailor Rolled Products find application in suspension, interior and exterior of a vehicle
• Specially designed for affordable vehicle weight optimization
• Tailor rolled products have a close tolerance with a high tensile strength
• Sheet thickness and material selection are optimized according to weight and function requirements

Camshafts
Mubea is the specialist for lightweight, highly functional manufactured camshafts and drive shafts. Using patented hydroforming assembly process, hubs of varying widths are connected to lightweight tubes through sheer friction. In this process, hydraulic pressure is applied in a tube functioning as the support and the tube undergoes plastic deformation against the hub. The plastic deformation remains in the tube and the particular add-on part is "stuck" on the tube due to its elasticity.

Features

• Manufactured with 100% control over the strain values, chosen for the joining assembly
• Thin-walled and high-stressed joining assemblies
• Quick and cost-effective changes can be included in add-on part contours, axial spacing, etc.

Tubular Shafts
Highly functional and low-weight drive/transmission shafts from tube materials are offered. The product range includes sun shafts, adapter shafts, input shafts, auxiliary shafts, main shafts, etc. These products are used in automatic and dual clutch transmissions as well as continuously variable and manual transmissions.

Features

• Low weight transmission shaft made from tube material
• Smooth surface and polished mandreal
• Functional interior profiles can be produced reliably and economically
• Available in different geometries with varying inner diameter, wall thickness, etc.
