What is the minimum order quantity for CNC machining?
The MOQ is 1 piece. Prototype and single-part orders are accepted alongside production runs, so you can validate a design before committing to volume without being pushed into a minimum that does not fit your stage.
What tolerances can you hold?
±0.003 mm on CNC milling, ±0.002 mm on CNC turning, and ±0.002 mm for precision grinding. Critical dimensions are verified on in-house Hexagon CMMs, with process capability Ppk ≥ 1.67 at the initial study on key characteristics and Cpk ≥ 1.33 on general characteristics.
Which materials do you machine?
Aluminum, stainless steel, carbon and alloy steel, brass, copper, titanium, magnesium and engineering plastics including ABS, POM, nylon, PTFE and PEEK. Incoming lots are XRF-checked against the mill certificate so the alloy you specify is the alloy you receive.
What are your lead times?
Roughly 3, 7 or 30 days depending on part complexity and the number of process steps. Simple parts ship in about 3 days, while parts with surface finishing or many operations fall into the longer 30-day tier.
Are you ISO and IATF certified?
Yes — ISO 9001:2015 (No. 116024/A/0001/UK/En), IATF 16949:2016 (No. 131941/A/0001/SM/En) and ISO 14001:2015 (No. 116024/B/0001/UK/En). IATF 16949 scope excludes product design under Clause 8.3, so this is a build-to-print operation.
How do you verify incoming material?
Every incoming lot is checked by XRF against its mill certificate before it reaches a machine, so mixed or mislabeled alloy is caught at the door. This prevents the most expensive defect in machining: a perfect part made from the wrong material.
What documentation ships with my parts?
CMM inspection reports, SPC control charts and material certificates ship with your parts. Every critical dimension carries a measured value rather than a pass/fail flag, giving you documented evidence of what you received.
Can you bundle surface finishing and heat treatment?
Yes — anodizing, plating, powder coating, painting, brushing and polishing can be bundled, along with heat treatment. In-house ovens reach 500 °C, covering aluminum and low-temperature steel stress relief; titanium stress relief above that is outsourced to a qualified partner.
What design files do you accept?
STEP, IGES and 2D drawings (PDF or DWG) are accepted. A toleranced 2D drawing alongside the 3D model is recommended, because the drawing carries the critical dimensions and tolerances the model alone does not convey.
How do I get a quote?
Send your STEP, IGES or 2D drawing to [email protected]. You receive a design-for-manufacturing review and a quote, usually within one business day, with any DFM issues flagged before you commit rather than discovered after the parts are cut.
How do you protect my drawings and IP?
Sensitive paper documents are stored in an access-controlled secure space and electronic data is kept on encrypted drives. A code of conduct covers confidentiality, data protection and IP protection, and data is disposed of responsibly under best practice.
Do you ship internationally, and to which markets?
Yes. Parts ship to Austria, Belgium, the Czech Republic, Denmark, France, Germany, Greece, Hungary, Ireland, Italy, the Netherlands, Spain, Sweden and the United Kingdom in Europe; Brazil, Canada, Mexico and the United States in the Americas; China, Israel, Japan, Singapore and Sri Lanka in Asia; Australia and New Zealand in Oceania; and South Africa in Africa — based in China, serving customers worldwide. The sales team works in English, Japanese, Portuguese, Spanish and French, with after-sales partners in Japan, the UK, Canada and Australia.
A question not covered here? Email [email protected] — a direct answer, usually within one business day, with the numbers behind it rather than a canned reply.
Which materials and industries do you cover?
We machine aluminum, stainless steel, titanium, brass, copper, and Inconel, plus engineering plastics including PEEK and Delrin. These CNC-machined parts go into medical, aerospace, automotive, robotics, electronics and defense applications, with the inspection, traceability and documentation each sector requires before it places an order.
What buyers ask most
Three questions come up on nearly every enquiry. What is the minimum order? One piece - a single prototype can be machined, checked and iterated before any volume is committed. What is the lead time? Roughly 3 / 7 / 30 days depending on the material and the documentation scope, from a simple aluminium part to a full first-article package. What tolerances can you hold? ±0.003 mm milled and ±0.002 mm turned, verified on a Hexagon CMM, with Ppk 1.67 or better initial and Cpk 1.33 or better in production on critical characteristics. The answers are short because the capability is specific, not vague.
The answers behind the answers
The plant behind these answers is Dongguan Zhuohang Ltd - 6,800 m² in Hengli Town, Dongguan, 100+ CNC machines including Mazak VARIAXIS I-600 and INTEGREX I-250H S, and certification to ISO 9001:2015, IATF 16949:2016 and ISO 14001:2015 with the certificate numbers published and verifiable. The service area covers Austria, Belgium, the Czech Republic, Denmark, France, Germany, Greece, Hungary, Ireland, Italy, the Netherlands, Spain, Sweden and the United Kingdom in Europe; Brazil, Canada, Mexico and the United States in the Americas; China, Israel, Japan, Singapore and Sri Lanka in Asia; Australia and New Zealand in Oceania; and South Africa in Africa, with worldwide shipping from Dongguan. Contact Felipe Iglesias at [email protected] or +86 13126536955 with a drawing and a quantity for a specific answer to your specific part.
What the floor can actually prove
Behind the numbers is a floor you can walk. Dongguan Zhuohang Ltd runs 100+ CNC machines - the Mazak VARIAXIS I-600 five-axis, the INTEGREX I-250H S mill-turn, Brother SPEEDIO, and TSUGAMI, STAR and CITIZEN Swiss lathes - across 6,800 m² in Hengli Town, Dongguan. Every critical feature is checked on a Hexagon CMM under the 10:1 gauge rule, and the certificate numbers for ISO 9001:2015, IATF 16949:2016 and ISO 14001:2015 are published and verifiable. Capability is tracked with Ppk 1.67 or better at the initial study and Cpk 1.33 or better in production, which is the difference between a tolerance that is quoted and a tolerance that is held.
The same floor serves buyers worldwide - Austria, Belgium, the Czech Republic, Denmark, France, Germany, Greece, Hungary, Ireland, Italy, the Netherlands, Spain, Sweden and the United Kingdom in Europe; Brazil, Canada, Mexico and the United States in the Americas; China, Israel, Japan, Singapore and Sri Lanka in Asia; Australia and New Zealand in Oceania; and South Africa in Africa - with shipping from Dongguan. MOQ is 1 piece and lead times run roughly 3 / 7 / 30 days depending on material and documentation. Send the drawing and the quantity to Felipe Iglesias at [email protected] or +86 13126536955, and the quote comes back with the process behind it.
Your next step
A drawing and a quantity are all it takes to turn this page into a real part. Send a STEP or IGES model plus a 2D drawing carrying the tolerances, datums, material grade and finish, and name the quantity and the lead time. That returns an itemised quote - material, setup, cycle time, inspection - instead of a round number. If the drawing is not done, send what exists and the questions holding you back; starting the conversation matters more than waiting for a perfect package.
