Products

Leinweber Maschinen offers stand-alone and turnkey solutions for the brake pad manufacturers.  Below you find a brief overview.

DRY MIXING AND GRANULATION

Standard Granulate system includes 1 mixer and 2 parallel drying and cooling systems and a final particle size classifier system.

HOT PRESSING

Rotary System

Available in single or dual feeding versions. System Operation: fully automatic. Integration - Possible to direct connect to cure oven. Mold cavities - 6, 12, 18 and 24 press stations available. Tonnage friction – up to 65 tons per mold cavity (press station). Maximum friction product size — fits within a diameter up to 200 mm. Lot or batch size — very large (high volume system)

Linear System

Flexible system — possible to produce different formula, reference number and process parameters in each press module. Within each press module 2 different shapes or reference numbers can be processed of similar size. System Operation: fully automatic. Usable for passenger or heavy duty vehicles. Integration - Possible to direct connect to cure oven. Mold cavities — 1 or 2 per press module. Maximum friction product size — 190 x 80 mm or 270 x 125 mm

POST OVEN CURING

Continuous oven lengths vary, based upon product cure times and size. Integration manipulators accept the product from hot pressing and insert into the proper oven lane. Oven cured product exits directly into temporary storage containers when multiple reference numbers are produced. An optional cooling section can be included. For high volume applications product can pass through a cooling section and then can be directly connected to finishing operations.

MAGAZINES

Quick change standard system — typical 5 minute queue time at 8 parts per minute with passenger car part sizes. Large system — typical 15 minute queue time at. 5 parts per minute with commercial vehicle part sizes. Input magazine can be controlled by Central Control System in integrated systems. If a line stop occurs the input magazine will stop and then automatically restart when the line is restarted.

GRINDING

For Passenger Car Disc Brakes

Auto input / output. Up to 16 parts per minute output. 1,2, or 3 slots. Compound / straight chamfer. 100% thickness checking. All data collection / reporting options. Maximum part size — friction 86 x 200 mm and backing plate 100 x 220 mm. Pre-assembled dust collection system. Integration to other modules

For Heavy Duty Disc Brakes

Auto input / output. Up to 6 parts per minute output. 4 Stations: Surface grind, thickness check, slotter and chamfer. Maximum part size - friction 125 x 270 mm and backing plate 150 x 320 mm. Pre-assembled dust collection system. Integration to other modules

SCORCHING

For Passenger Car Disc Brakes

System operation: manual, semi or fully automatic. Maximum scorch temperature 800^°C (1470^°F). Adjustable temperature and pressure. Pressing forces — 6.6 to 25 kN (1500 — 5600 pounds force). Maximum heated area — 230 x 110 mm

For Heavy Duty Car Disc Brakes

System Operation: fully automatic. Maximum scorch temperature 800^°C (14750^°F). No pressure on part. Maximum part size - 150 x 320 mm

SHOT BLASTING

Backing plates cleaned in up to 3 lanes integrated into a total finishing line or powder paint line. Shot blast system started and stopped by central control.

POWDER PAINTING

OEM quality. Productivity — Leinweber provides modular coating systems with various output rates to suit your production situation. Coating range between 20 to 50 microns. Gun and belt cleaning system

Powder reclaim (recycle) system. Fire detection and fire extinguisher systems.

INFRARED OVENS

Up to 4 lanes. OEM quality. Oven length based upon part length and output rate and your production requirements.

ANTI-NOISE SHIM ATTACHMENT

System Operation: manual or automatic. OEM Quality. Maximum shim size 200x100 mm, backplate 240x100 mm. Variable parameter settings for pressure, temperature and time. High temperature capacity: 260^°C (500^°F). High tonnage: up to 5.0 tons.

COOLING MODULES

Integrate into total production line. No change over required for part change.  Small space requirements.
