Quality inspection

We always conduct quality inspections very carefully, and send you reports, pictures and videos, so you will be kept most up to date of what is going on and what you are going to receive.

Visual inspection

We present all imperfections in front of you and let you decide if they are acceptable. Here are a few examples:

A small dent of about 0.5mm wide on the sharp edge. This is considered acceptable with a small percentage of parts.
surface waviness caused by cnc turning of thin-wall structure
Surface waviness caused by CNC machining on thin-wall structure. This is quite common in low volume production.
aluminum anodizing defects
We found white marks on some of the parts, they are not too noticeable if looking from other angles, but we still rejected this kind of parts.

Dimensional results report

It is not just to take the measurements, but more importantly, to do it correctly.

We will take several readings to make sure the measurements are taken correctly.

Factory tour

As a sourcing company, taking advantage of our sourcing skills and solid presence in local area, we always choose to with CNC machining factories that can deliver low prices and good quality.

The processes of working with us

Please send us the drawings and quantities to be quoted. The 2d drawings are better in pdf or dwg formats, the 3d drawings are always good to come with them. Include necessary information like the material spec, dimensional tolerances, surface roughness.

We will review your drawings and quote the prices. Sometimes we will include tooling/fixtures in the quote if they are needed.

If you accept our prices and want to move forward, please send a sample order and pay the sample fee which includes the shipping cost of samples. The samples fee is refundable if later our samples do not meet the specs.

We will double check the drawings and make sure we the specs are clearly defined. Sometimes we will create the drawings by ourselves to make them more clear and accurate.

We will produce the samples according to the drawings and specs. A typical lead time will be 3 to 10 days, depending on the complexity of parts and if there are tooling/fixtures to be made. Then we will send the samples to you by couriers.

If you approve the samples, please send the production order when you are ready, and send the deposit at the same time. Our usual payment term will be 30% deposit before order production, and 70% before order shipment. The payment term will be different sometimes.
