Question 1

What are the sample development costs and lead time? Is there a minimum order quantity?

Accepted Answer

Our sample development is priced through negotiation, and the sample fee can be deducted from future mass production costs. Standard samples are completed within 10 working days, with expedited options available upon negotiation. The minimum order quantity is 100 pieces.

Question 2

How is the CNC machining cost calculated? Why are your quotes sometimes higher than others?

Accepted Answer

Our CNC machining cost is calculated as 'material cost + machine hour cost + tooling/fixture cost + surface treatment + profit'. The higher price is influenced by factors such as equipment precision, full inspection of product quality for each batch, and the use of high-end spindles.

Question 3

How do you ensure machining quality? What inspection equipment do you have?

Accepted Answer

We are equipped with measuring instruments such as CMM (coordinate measuring machine), roughness tester, and air gauge. We perform 100% inspection of critical dimensions and can provide full inspection reports.

Question 4

How are quality issues handled?

Accepted Answer

If any quality issue arises with our products, we will respond within 24 hours. Once it is confirmed to be our responsibility, we will either remake the products or issue a refund at no cost, and we will also bear the shipping cost for emergency replacement.

Question 5

What surface treatments and heat treatments can you provide?

Accepted Answer

We can provide treatments such as anodizing, electroplating, blackening, sandblasting, and vacuum heat treatment, depending on the material properties. These require an additional 3 days. We can also outsource the processes while maintaining unified quality control.

Question 6

What drawing formats do you require, and can you sign a confidentiality agreement?

Accepted Answer

We accept 3D models (STEP/IGS) plus 2D drawings (PDF/DWG). The 3D files are used for programming, and the 2D drawings are used for dimension and tolerance annotations. We are able to sign an NDA, and after project completion, we will destroy or return the drawings.

Question 7

Can you machine complex parts, such as deep holes, thin walls, or freeform surfaces?

Accepted Answer

Yes, we can machine complex parts. We have produced aluminum alloy thin-wall parts with a wall thickness of 0.8 mm for customers. We are equipped with 5-axis simultaneous machining equipment, which can machine impellers and other freeform surface parts. For deep-hole machining, we use gun drilling solutions.

Question 8

What if the design drawing is modified midway?

Accepted Answer

We allow minor adjustments before first article approval. For parts that have already started processing, additional labor and tool wear costs will need to be negotiated. We will try our best to accommodate the changes.

Question 9

Which industries or types of parts are you specialized in? Do you have relevant certifications?

Accepted Answer

Our CNC machining products cover industries such as lighting, aerospace, medical, automotive, and robotics. We are certified with ISO9001, CE, and RoHS, and these certifications can be provided upon customer request.
