Mouldings de-binder furnaces cool
rapidly
Three customised furnaces, designed for burning off binders in injection-moulded components, feature fast cooling cycles and a sintering process, to reduce total processing time.
Lenton Thermal Designs has delivered three customised furnaces with fast cooling performance for heat-treating powder injection moulded components in controlled atmospheres at temperatures up to 1000 deg C Built for Singapore-based Solid Micron Technologies, the furnaces burn off binders in injection-moulded components at between 400 deg C and 500 deg C

Furnaces sinter orthobiologic materials
Used in the manufacturing process for tricalcium phosphategranules, two custom furnaces are used to sinter orthobiologic materials in clean room conditions at closely controlled temperatures.
Custom-built furnace has integral weighing system
Lenton Thermal Designs has custom-made a test furnace for Jaguar and Land Rover, providing a method for measuring the soot content of exhaust filters fitted on the company's diesel-engined vehicles.
They then sinter them at approximately 1000 deg C.
The accelerated cooling system reduces the complete processing cycle to 8h and maximises throughput.
The furnaces have cylindrical gas-tight stainless steel retorts with capacities of 170, 340 and 510 litres.
These are fed with nitrogen gas throughout the heating process to prevent oxidisation of the components.
Three-zone heating control ensures uniform and consistent temperatures throughout the retorts.
After-burners are fitted to minimise exhaust emissions to atmosphere, and all electrical equipment has been designed for operation in ambient temperatures from 34 deg C to 40 deg C and relative humidity of 98%.
In order to accelerate the cooling phase of each cycle, Lenton has supplied a heat exchanger that can be moved between the furnaces and used to force-cool the hot nitrogen gas.
The gas is then circulated within the retorts.
This system has reduced cooling times from about 6h in the case of a full load in the largest furnace to about 3h, allowing a full cycle to be completed in a single shift.
