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

 

  • Compound Stamping Dies:

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.

 

  • Notching Dies
  • Short-run stamping tool
  • Progressive Staking Dies
  • Laser-cut or wire erosion

 

QUALITY :

Our stringent quality management ensures product consistency covering all processes from raw material procurement to finished goods production. The products and processes pass through stringent quality tests benchmarked with global standards.

Our manufacturing facilities are ISO 9001:2015 or IAFT16949:2016 certified. Our greatest asset is delivering outstanding product quality and first-class service to our customers globally.

GUARANTEE:

The Toolroom is responsible for the maintenance and repair of all production tooling. We will maintain all customer tooling at no charge for the guaranteed life of the tooling.

PRICE:

Our components are efficiently manufactured to give our customers very competitive pricing without compromising product quality.

DELIVERY:

We offer warehousing locations across the UK and Europe that are set up for stocking programs and deliveries to match customer specific manufacturing and inventory requirements.
