TOOLING OPTIONS
Most tooling is designed & manufactured by us with our core expertise and Tool Modelling, Tool Path Generation, VMC Machining, EDM Processes, and other related activities, which are done in house to cut down & maintain development times at the lowest. We take responsibility for proving the components of the dies made by us and we maintain the tooling at no extra cost for it s life.
Short run and prototype requirements can be produced by notch tooling, wire EDM or laser cut. The tooling cost is low but the piece part price is significantly higher.
Intermediate tooling for quantities of up to five million can be designed using our proprietary extensive Master Die Insert Program, which offers all the advantages of a full production tool but at a much lower cost.
For higher production volumes, Carbide Progressive Tooling is available with guarantees to 100 million parts, which offers all the advantages of a full production tool but at a much lower cost.
We can design, manufacture singled, doubled and tripled row interlocked / skew / Indexed, buckle bonded, rivet bonded, stamping tool as per customer requirements.
Carbide Progressive stamping Dies:
Ideal for high volume requirements. The cost of the stamping tool is high, but the unit price per piece of stator and rotor core becomes more economical.
Progressive stamping die can be used to stamp loose sheets or auto-stacked cores.
We can also build a skewing mechanism for the rotor or 180-degree indexing feature for the stator.
We design the die for stamping stator and rotor core, outsource die parts for fabrication, then assemble the progressive stamping die in the house.
Currently, the thinnest material we can stamp with a progressive stamping die is 0.2mm.
The quality: tolerance of spare parts is within 0.002mm, tolerance of feeding length is within 0.003-0.005mm, and roughness is within ra 0.04-0.1.
Efficiency: stamping speed reaches 300-1200 strokes per minute (depend on product type)
durability: single shot die life 200-600 million times (according to the material and set), a comprehensive life 1.2-2.5 million times.
TYPE OF DIES:
· Index die
Dies performing automated stacking through the rotation of each lamination at a fixed angle (30°, 45°, 60°, 90°) while performing core stacking
(improve concentricity and thickness deviation of stack height)
· Index + Skew
Materialize the fixed angle and minute angle at the same time while performing core stacking
· Skew die
Dies performing automated stacking through the rotation of each core at a minute angle while performing core stacking (reduce motor noise)
· Wrap up core die
· Segment core die
The ideal option for small quantity rotor-stator production.
The tooling cost is cheaper compared with progressive stamping die, but the labour cost is higher. Only loose sheets can be produced from a compound tool.
