OEM assembly lines do not buy inserts — they buy consistency. Robotic pick-and-place and automated induction brazing demand inserts that fit the same way every time, with tolerances tight enough to prevent jams and rejects. SENTHAI manufactures custom carbide inserts for exactly this kind of precision supply. The SENTHAI insert sizes and shapes describes the standard range and custom capability.
OEM Insert Supply
OEM supply is a program, not a purchase: agreed specifications, approved samples, scheduled runs, and lot traceability. The supplier becomes part of the OEM’s quality system, which is why process documentation matters as much as price.
Custom Insert Manufacturing
Custom inserts are manufactured to drawings and specifications, covering unusual shapes, sizes, and configurations. Custom work moves through engineering confirmation and sampling before production.
Quality Requirements
Quality means dimensional tolerance, batch consistency, and surface condition for brazing. Each is measured and documented per lot. Research on cutting edges — NCHRP 06-19 — recommends measurable quality controls for specification-driven supply.
Tolerances
SENTHAI holds dimensional tolerances within ±0.02mm — ideal for high-speed robotic pick-and-place and automated induction brazing. Tight tolerances prevent machine jams and increase production throughput.
Lead Times
OEM programs schedule production ahead of season, with safety stock buffers for the North American winter rush. Agreed lead times protect assembly lines from supply gaps at peak demand.
Robotic Pick-and-Place Tolerances
Automated assembly needs inserts that seat consistently in milled slots. ±0.02mm tolerances ensure every insert fits the same way, keeping robots running and rejecting nothing.
Custom Shapes from Drawings
Beyond standard sizes, SENTHAI manufactures custom-shaped inserts to your drawings and specifications. Send the drawing or sample, and engineering confirms the profile before sampling.
Batch Consistency for Assembly
Compression molding and vacuum sintering with controlled parameters deliver uniform density and structure across batches. Consistency is verified by QC and documented per lot — the assurance an assembly line needs.
Safety Stock for Seasonal Demand
SENTHAI maintains safety stock buffers and production scheduling around the North American snow season, ensuring lines never stop for lack of critical carbide components during peak demand.
Starting an OEM Supply Program
- Send drawings or samples with your specification.
- Confirm the production profile with engineering.
- Approve samples before volume.
- Agree on schedules, MOQ, and lead times.
- Receive batch QC records with each shipment.
Frequently Asked Questions
What tolerance do OEM assembly lines need?
±0.02mm is the precision standard for robotic pick-and-place and automated brazing — it prevents jams and rejects.
Can SENTHAI make custom insert shapes?
Yes — custom-shaped carbide inserts are manufactured to your drawings or samples.
How is batch consistency guaranteed?
Controlled sintering, density and hardness checks, and per-lot QC records verify every shipment.
How do you handle seasonal demand spikes?
Safety stock buffers and production scheduling keep OEM lines supplied through the North American winter rush.
