Company profile

A factory built
around tolerance.

Founded in 2006 in Luqiao District, Taizhou — a machining shop that grew into a forging, casting, laser cutting and CNC production partner for customers in 20+ countries.

01 — Our story

Built on the shop floor.

The company began in 2006 as a small CNC turning and milling shop in Luqiao District, Taizhou — a region built on pump, valve and motor manufacturing. The first work was short runs of turned and milled parts for local OEMs, delivered on a date they could plan around.

As order volumes grew, so did the process chain. Forging, casting and laser cutting moved into the same supply route and, more importantly, into the same quality system: one drawing, one inspection plan, one shipment. Today CRL ships machined components in carbon steel, stainless steel, cast iron and aluminum to customers in Europe and North America — from prototype quantities to repeating production releases.

The floor is organised around first-article approval and in-process checks rather than end-of-line sorting. Every lot leaves with material certificates, dimensional records and a packing list that matches the drawing revision it was made to.

How we are organised

Engineering & programming (12) · Production (120) · Quality (14) · Tooling & maintenance (9).

One engineer owns each customer drawing from DFM review to final inspection, so the person who quoted your part is the person you can ask about it.

02 — Direction

Mission, vision, values.

Why we come in every morning, where we are going, and the handful of rules we do not break.

M / 01

Mission

Turn a drawing into a part that fits the first time — on the date we quoted, at the tolerance we agreed, with the paperwork that lets you prove it.

V / 02

Vision

To stay the supplier OEMs call when the part is difficult, the volume is modest and the deadline is real — and to be judged on the second order, not the first.

V / 03

Values

Precision over speed. Say what we can hold, then hold it. Own the whole lot, not just the good ones. Write it down. Answer the phone.

03 — Milestones

Timeline.

Two machines in a rented unit in 2006, six process routes and a metrology lab today. The steps in between are the same steps our customers grew with.

  • 2006 Company founded in Taizhou

    CHENGRL MACHINERY (TAIZHOU) COMPANY LIMITED is established in Luqiao District — CNC turning and milling for local pump, valve and motor manufacturers.

  • 2009 First CNC turning cell

    A second turning cell and the first CAM programming station arrive; repeat work for two local valve makers moves in-house and the shop stops quoting from a fax machine.

  • 2014 Casting partnership established

    Steel and iron casting partners come under CRL drawings and incoming inspection, so castings reach the machining floor ready for the first op instead of being reworked there.

  • 2018 ISO 9001 certification & CMM lab

    A temperature-controlled metrology room with a CMM; first-article reports, material certificates and PPAP documentation become standard on every shipment.

  • 2023 5-axis and automated turning

    5-axis machining and automated turning cells added for complex parts that used to need three setups — one clamp, one datum, one inspection plan.

04 — People & compliance

Leadership & certifications.

Quality system

Every drawing gets an inspection plan before the first chip is cut: which features, which gauge, how often. The plan is written by the engineer who quoted the job and signed off by quality, so the tolerance you argued about in the RFQ is the one being measured on the floor.

Lots ship with material certificates, dimensional records matched to the drawing revision and, on request, PPAP documentation and a first-article report.

Traceability

Heat numbers are recorded on the job card at goods-in and carried through to the packing list, so a finished part can be walked back to the mill certificate it was made from.
