Mass production houses
Usually focused on injection and CNC machining of mass production workshop, in the operation of tens of millions of parts can reduce the price of parts. Their niche is shaved by high-speed repeats in the way of seconds and pennies, especially when running "lights out" or fully automated factories. Early construction costs may be high. Most suppliers usually do not like to do the prototype because they are not cost effective.
Quality control: generally good. Production companies specializing in highly managed industries will usually meet the required standards. Quality control of commercial parts will be at a lower but appropriate level.
Turnaround time: Large capacity is usually good and predictable. If the supplier has to get the equipment to produce your parts, it may cause delays and many people will do it.
Volumes: big orders are their bread and butter. Put the equipment into a project, such as a molding unit that can run parts at one time.
Production costs: As the focus on efficient operation, the greater the volume, the higher the cost. However, if you only need dozens or hundreds of parts, then they are more expensive.
