01 / COOKA CAPABILITIESMaterials & R&DCarbon-film formulation, track processing and electrical response.
01 / CARBON-FILM RAW MATERIAL R&D
Material research.
At the source.
Cooka’s laboratory develops carbon-film raw materials for resistive elements. Material formulation and electrical response support the component development process.
- Raw-material developmentCarbon-film material research for the resistive element.
- Element processingBring the material and track geometry into the component.
- Response evaluationReview the material’s electrical behaviour before assembly.
Carbon-film making
Roller processing prepares the material for the resistive element.
Carbon-film printing
Screen printing forms the resistive track on the substrate.
02 / COOKA CAPABILITIESManufacturingPrecision machining, assembly and shipment preparation.
02 / MANUFACTURING & DELIVERY
Precision processes.
One production workflow.
Repeatable processes.
Connected production.
From mechanical parts to the assembled component, Cooka brings machining, automated processing and workbench assembly into one production workflow.
- Mechanical interfacesShafts and housings follow the component drawing.
- Component processingProduction fixtures support a consistent processing route.
- Assembly & deliveryBring the resistive element, mechanics and connections together before packing.
Precision machining
Shafts, housings and mechanical interfaces follow the component drawing.
Component assembly
Resistive elements, mechanics and connections come together at the workbench.
Packing & finished goods
Cooka cartons, organised storage and shipment preparation for completed parts.
03 / COOKA CAPABILITIESQuality & TestingDimensional inspection, calibration and component evaluation.
03 / QUALITY & TESTING
Calibrate the response.
Inspect the component.
Dimensions & interfaces
Optical inspection checks the component’s mounting, shaft and connection features against the drawing.
- Dimensional inspectionMeasure the critical geometry and installation interfaces.
- Electrical responseCheck the resistance response through the defined movement.
- Reliability evaluationEvaluate the component under the agreed operating and test conditions.
Rotary response adjustment
A rotary fixture relates the component’s electrical response to its angular position during adjustment.
Linear response adjustment
A linear fixture relates the resistive track’s response to position along the defined stroke.
Component evaluation
Fixtures and instruments support electrical and series-specific evaluation.
