At REKO, we believe professional CNC machining starts with clear communication.
Our FAQs are built from
real questions asked by engineers and purchasing teams around the world — covering materials, tolerances, lead
times, quality control, and production processes.
Behind every answer is a structured service system, experienced engineers, and a proven workflow designed to
reduce risk, avoid surprises, and deliver consistent results.
If you don't find your answer here, our team
is always ready to support you with fast, direct, and honest communication.
FAQ'S
Tolerances, materials, surface finishes, and production consistency for automotive applications.
FAQ'S
Strength, lightweight design, surface treatment, and batch production for motorcycle parts.
FAQ'S
Precision, weight optimization, finishes, and performance requirements for cycling parts.
FAQ'S
High-pressure tolerance, sealing surfaces, material selection, and quality control standards.
Please provide us the following information together with your inquiry.
Our standard order process is as follows:
This process ensures clarity, traceability, and on-time delivery.
Yes. We offer expedited machining services.
We have dedicated machines reserved for urgent projects to
shorten lead times whenever possible.
We accept multiple payment methods, including:
Please contact us if you have specific payment requirements.
Our factory is located in Bao'an District, Shenzhen, China, close to Shenzhen International Airport.
This
location allows efficient logistics for international shipments.
Quality is controlled at every stage of production:
Inspection reports can be provided together with shipment.
We ensure delivery reliability through:
This structured system helps prevent delays and ensures smooth execution.
Our machining tolerances comply with ISO 2768 standards:
Final tolerance capability depends on part geometry and material.
Commonly used materials include:
Material selection depends on strength, weight, environment, and cost.
Yes. Customer-supplied materials are acceptable if they meet processing and safety requirements.
Please
contact us in advance to confirm compatibility.
Material selection depends on:
We provide free DFM support to help you choose the most suitable material.
Yes. Harder or difficult-to-machine materials may require longer machining and inspection time.
Aluminum and ABS are commonly used for prototyping due to their machinability and cost efficiency.
Yes. Materials such as PEEK and 316L stainless steel are available.
Please specify applicable standards
during your inquiry.
Generally no.
Engineering plastics offer good performance, but metals are preferred for high-load or
structural applications.
We recommend finalizing material selection before production starts.
Changes after machining begins may
result in additional costs or delays.
Yes. Recycled ABS, recycled PE, and certain aluminum alloys are available.
Please inform us of any
sustainability requirements during inquiry.
Surface finishing enhances appearance, corrosion resistance, durability, or functional performance of CNC-machined parts.
We offer:
Anodizing is mainly suitable for aluminum and its alloys. It is not applicable to ferrous metals or most plastics.
No. Stainless steel cannot be anodized. Electroplating or passivation is more suitable.
Yes. Please specify Ra or Rz requirements during quotation or order confirmation.
Yes. Most surface treatments add a coating layer, which may affect tight tolerances. Please inform us in advance if tolerances are critical.
In some cases, yes.
For example, sandblasting before anodizing. Process compatibility will be evaluated by
our engineers.
Yes. Custom colors for anodizing and painting are available.
Please provide Pantone or RAL color codes.
Yes. Treatments such as anodizing, powder coating, and passivation significantly enhance corrosion resistance.
Typical coating thickness:
