How To Choose Your CNC Machining Metal Manufacturer

Precision computer numerical control (CNC) machining is one of the most recent innovations in the manufacturing sector. It allows manufacturers to increase production speed and efficiency while reducing errors. It also enables the usage of special equipment to transform big chunks of material into more precise components.

Whether you have a large or small project that requires CNC machining, choosing the right manufacturing company to partner with is crucial. You must plan your process for selecting the ideal service provider for your needs to avoid expensive and time-consuming mistakes.

This article will walk you through the key factors when choosing the right CNC machining metal manufacturer for your project.

Considerations When Choosing a CNC Machining Metal Manufacturer

Choosing a great manufacturer significantly contributes to a project’s success. However, choosing a reliable service provider is challenging, especially if you are unfamiliar with CNC machining metal services. Here are some factors to take into account that will help you choose the best:


In general, the longer a manufacturer has been practicing CNC machining, the more competent the manufacturer gets. If the company has been in the precision machining industry for more than 10 years, it should have amassed a great deal of experience in the field. For instance, they can usually handle difficult-to-process metals.

However, it is necessary to conduct additional research to determine whether they have previously worked on similar projects. Even if a company has decades of experience, it may not be the ideal option if it cannot meet your specific needs.

Equipment and Material Availability

A reputable manufacturer must have the main CNC machines. Among them are machining centers, milling machines, lathes, W-EDM machines, drilling equipment, and many others.

Additionally, you should determine if they offer a vast selection of metals. The following are commonly used metals for CNC machining:

  • Carbon steel
  • Stainless steel
  • Aluminum
  • Titanium
  • Brass
  • Copper
  • Magnesium

Quality Control

The quality control of a company can make or break your project. To ensure that your machined components are of the highest quality, confirm that the manufacturer has extensive measuring and testing capabilities. From the metal selection until shipment, a qualified CNC machining manufacturer should inspect each procedure and present you with testing results.

Design Expertise

Choose a service provider with excellent design capabilities because they are well-versed in design constraints and machining requirements. They can also quickly assess the machinability of a component, provide suggestions for changing it to better meet your standards, or create the design for you.


Low pricing is not indicative of high-quality work. Choosing a company based solely on pricing could waste time, money, and effort as you seek a second facility to fix the initial service provider’s poor performance. A reputable machining manufacturer will always allow the customer to retain the maximum profit to maximize their own.

You can obtain quotations from various manufacturers for comparison. Then, choose the company that provides the best combination of quality, turnaround time, and price.

After-Sale Service

After-sale service is crucial, especially for custom CNC machining metal services. Ensure that the company will provide samples to determine the quality of the machined component.

Occasionally, you may not receive the correct part the first time, necessitating the request for a second sample. In such situations, confirm whether the manufacturer is willing to redo everything.

How to Choose Your CNC Machining Plastic For Manufacturing

Plastics' versatility and multiple benefits make them one of the most valuable engineering materials available today. However, this does not mean you should make plastic prototypes using any machining technique. If the material and method are incompatible, the manufacturing process will not be successful and will not provide the desired results. Each material has distinct characteristics that make it ideal for a particular use. Computer Numerical Control, or CNC machining, is one of the many alternative technologies for making prototypes. It is a computerized manufacturing process in which software and codes control the motion of production equipment, including grinders, lathes, and turning mills. These are used to cut, shape, and create various prototypes and parts. If you use plastic material to design and manufacture parts, they should be CNC machined. There is a plethora of machinable plastic to select from for plastic machining, each with its properties and capabilities. CNC-machined plastic components make excellent prototypes and are readily available. Before machining, select the most suitable and optimal CNC machining plastic for your product. To help you with this, here are the different CNC machining plastic and a quick look at their qualities and capabilities!


ABS is a thermoplastic polymer with strong impact resistance, low electrical conductivity, and high chemical resistance. Due to its adaptability, ABS is widely beneficial and one of the known plastic compatible with CNC machining. Some applications where ABS is utilized are producing automobile components, toys, and sporting goods. On the other hand, while it is less expensive than other plastic materials, it is essential to note that it cannot sustain high temperatures for an extended period.


Nylon is a polyamide polymer and a strong and durable plastic used for various purposes. It has good machinability, moderate flame resistance, and high strength, among other advantages. Nylon tolerates high temperatures and is resistant to wear. In addition, it is chemically and thermally resistant and has the rigidity and strength to withstand deformation under load conditions. These characteristics make it an excellent material for insulators, bearings, wheels, and consumer electronic enclosures. Nylon is a fantastic option for applications that require inexpensive, sturdy, and durable components. Electrical insulation, medical devices, circuit board mounting hardware, vehicle engine compartment components, and aerospace components are the most prevalent applications for nylon. Many of these applications serve as a cost-effective substitute for metals. Additionally, glass-filled nylon is a common material that is excellent for CNC machining.


PMMA (Poly Methyl Methacrylate) plastic is acrylic's chemical makeup, also known as Plexiglass and Luctie. PMMA is an alternative to glass and light pipes since it is durable, transparent, scratch-resistant, and impact-resistant. Additionally, it may be easily glued using acrylic cement. Other popular applications include vehicle light components, light tubes, tanks, display panels, clear enclosures, food storage containers, and lenses or other optical engineering components. If a machined surface requires transparency, it can be polished as an additional post-processing step. Acrylic surfaces that have been machined lose their clarity and acquire a frosted, translucent appearance. As a result, it is generally advisable to indicate whether or not an acrylic component should be left at a stock thickness to preserve transparency.


HDPE is an abbreviation for high-density polyethylene. Its crystalline structure makes it naturally opaque and waxy, but it can also be dyed black. HDPE offers excellent chemical resistance, electrical insulation, and a slick surface. It has a low friction coefficient and good low-temperature impact resistance. Additionally, it is inexpensive and durable for CNC-machined plastic parts. HDPE is used in gasoline tanks, plastic bottles, fluid pipes, and other applications. Due to its chemical resistance and slipperiness, it is ideal for producing plugs and seals, but it is also an excellent option for weight-sensitive or electrically sensitive applications. The sole disadvantage of this material for CNC machining would be its low strength, particularly in tension and bending, making it susceptible to stress fractures.

Delrin or POM

Delrin or Polyoxymethylene (POM) is a suitable CNC machining plastic for high-friction, tight-tolerance, or stiff applications. Its reliability and durability make it popular in commercial markets. In addition, Delrin has the advantage of its superior resistance to impact, chemicals, moisture, and fatigue. Delrin is utilized in gears, bearings, bushings, fasteners, assembly jigs, automotive, construction, and electronics components. The downside, however, is that Delrin's slipperiness makes it difficult to glue. The material's inherent tensions make it warp-prone in thin or asymmetrically removed portions. Overheating Delrin or POM can cause harmful off-gassing.


Polycarbonate is the most durable plastic for CNC machining. In addition, it is one of the world's most frequently CNC-machined and recycled plastics. It is offered commercially in a black hue, despite its inherent milky-blue transparency, which is glossy. Polycarbonate offers strong impact resistance, rigidity, and temperature stability. It is 250 times more impact-resistant than glass and more resilient than acrylic. This quality makes it suitable for robust, transparent plastic applications, such as CDs, DVDs, mobile phones, and bulletproof glass. Additionally, pure polycarbonate is scratchable and wears quickly, which is why it is post-processed with anti-scratch coatings and vapor polishing to improve wear resistance or optical clarity.
