When It’s Necessary to Make a Sample Firstly?

As per our experience on CNC machining and relative manufacturing service, in below conditions, it is strongly advised to make a sample to confirm the quality before bulk production, just in case.

1. Buyer doesn’t have capability to make engineer drawing.
If buyer can only provide physical sample and can’t make engineer drawing, this means the dimension tolerance is not clear for both buyer and factory, the manufacturing risk is very high if we directly proceed bulk production, so it is strongly advised to proceed a sample for quality inspection, including fitting test, surface quality checking, before bulk production, just in case.

2. First Time to Work with Henrong.
Everything has first time, if it is the first time you work with Henrong, to better cooperate on the bulk project, it is advised to make a sample or trial order to get familiar with  our scientific and efficient working process, we can do Paypal for order amount less than USD1000, so start a try with Henrong, you will like it!

3. Manufacturing quantity is Higher than 500PCS per Item.
Generally Henrong can provide a FREE sample for your quality confirmation if bulk order is placed with purchase quantity per item higher than 500PCS (it needs to check the component detail firstly before confirming to provide free sample), so why not use this policy to get sample for quality inspection in advance before bulk production, this method can effectively improve the manufacturing correctness for you.

Henrong has professional manufacturing engineers and advanced facilities to help you make custom parts with top quality with reasonable cost. We look forward to starting long term cooperation with you!
