PILLAR 01 / DRAWING-BASED

Precision Machining Sourcing

Turn drawings, samples, and measurable old parts into a clearer China-side machining route.

CNC machining production floor used to evaluate precision machining capability — Capability starts with the process route, not a factory name.

FROM EVIDENCE TO PROCESS

One drawing can lead to very different supplier routes.

Batch size, tolerance, material, process sequence, tooling, surface treatment, and inspection expectations determine which machining source is suitable.

CNC turning

Shafts, pins, bushings, sleeves, threaded and rotational parts.

CNC milling

Blocks, brackets, plates, housings, fixtures and multi-face parts.

Grinding & close finishing

Requirements where final size, form or finish needs a controlled route.

Small-batch custom work

Trials, mixed low volumes, replacement parts and second-source projects.

WHAT THE PROJECT CAN LOOK LIKE

From machined components to packed small batches.

The visual evidence changes with the request. Drawings, samples, process photos, and packing evidence help keep supplier discussions concrete.

Precision machined components grouped for sourcing review — Drawing-based partsGeometry, material, finish, tolerance and batch size.

Custom threaded machined fittings and compact interface parts — Custom interfacesThreads, sealing, material and application context.

Small batch custom machined parts organized for shipment — Small-batch follow-throughApproved changes, quantity, labels and packing.

MACHINING SOURCING ROUTE

Follow the manufacturing logic, then compare the commercial offer.

Molitech organizes supplier questions, quotation differences, samples, approved changes, and agreed shipment evidence.

Review the evidence

Drawing revision, material, tolerance, finish, quantity and open questions.

Match process capability

Turning, milling, grinding, combined processes, tooling and batch fit.

Compare the same basis

Unit price, tooling, MOQ, lead time, sample route and inspection scope.

Follow sample and order

Supplier replies, revisions, approvals, order details and agreed evidence.

GOOD FIT

A reviewable part with enough evidence to clarify before quotation.

Standard sourcing: RFQ clarification, supplier search, quotation and sample follow-up, order coordination, and agreed basic shipment evidence.

Scope separately: FAI, supplier audits, process monitoring, PPAP-style documents, special compliance, and advanced inspection.
