When you’re ordering custom parts from an outside machine shop, it’s important to know whether the machine shop can make a satisfactory part on time before you commit a purchase to that particular shop. Here are a few useful questions that you should keep in mind when asking the custom parts manufacturer before you decide to purchase the parts from the machine shop:

1. Does the material used is apply to the drawing?

Material choice is incredibly important in the manufacture of custom components. However, each country has its own named brand for the same material, if the machine shop is in the overseas, do they have the ability choose the right brand name material? When a custom metal parts manufacturer uses the right material for the job, you can get the most bangs for your buck. For example, the below chart is for steel material.

2. Can you make the perfect parts?

Mass production is different from the samples stage, because each part has to fall within a very specific set of measurements. This requires the machine shop to always have a high attention for the quality in their mind. Otherwise there will have a collection of worthless scrap on their hands.

If some custom parts have the plating process, there will be some spots on the surface. Hence, this will need the 100% selection process before packing and also the package could prevent the parts from damage during the shipping process.

3. What is the delivery time to fulfill the order?

If you are looking for the CNC machine shops from outside, it is important to know how fast they can fulfill the production including the shipping time. You may want to do some independent research and check with the manufacturer’s previous clients to ask them how quickly their orders arrived after finalized the order.
