Process

Drawing in. Inspected finished part out. Eight stages, one quality system.

Every order at Wolfer follows the same eight-stage workflow — from drawing arrival to final inspection — so QC documentation looks identical across products and across customers.

Capabilities

Eight stages, one quality system

STEP 01

Drawing review

Engineering review within one business day. We flag any feature that's ambiguous, unmanufacturable, or where a substitution would save the customer money.

STEP 02

Quote

24-hour quote with line-item pricing — raw material, cutting, heat-treatment, grinding, inspection. Customers see what they're paying for.

STEP 03

PO + material

Customer PO confirmed. Material ordered from our steel partners the same day; typical bar-stock arrival in 3–5 days.

STEP 04

Cutting

Turning, hobbing, milling per drawing. CNC programs reviewed by the plant manager before first cut.

STEP 05

Heat treatment

Carburize / nitride / induction / quench-temper as the drawing demands. Heat-treatment record attached to part lot.

STEP 06

Finish grinding

Tooth flank, bearing journal, mating surface ground to drawing tolerance — after heat treatment, so distortion is removed.

STEP 07

Inspection

CMM dimensional check; gear-type parts verified on the gear inspection center for pitch, profile, lead and runout. Data archived in-plant by lot code as the shipment-release basis.

STEP 08

Packaging + ship

Anti-corrosion oil, lot-coded labels, customer's preferred packaging spec. Air or sea freight to international destinations — DDP terms available.
