Which parameters play a vital role in selecting a full-service precision machined parts manufacturer?

Selecting the CNC machined part supplier from China can be a challenging task. China has a vast market of CNC machined parts manufacturers. In fact, it is one of the biggest suppliers of CNC machining parts around the globe. Below mentioned are the main factors you should know before selecting full-service precision machined parts manufacturer from China.

Customer Service

If you are ordering Piezas mecanizadas por CNC directly from China without an agent or an employee, then their customer service is a very crucial part of this whole process. The communication is remote and it is important to have quick answers from the other side. So, the supplier should have a professional English-speaking representative who responds quickly to your answers.

Check  the Exact Location of the supplier

China is a huge country and it is important to know the exact position of the supplier to check which seaport is nearer to the factory and what is the distance of the factory to the port because it affects the overall cost.

This also helps if you work with several suppliers in China you can source your order to the new factory. It will save your freight and import cost. By knowing the exact location you can also find the airport nearby for a future visit.

Ask for Samples

Before making the order make sure the supplier is willing to provide samples for the approval and its cost. Factories that are willing to work with new customers always provide samples free of charge or with minimal fees to convince them and make sure the buyer is satisfied with what he/she gets.

Nosotros en DEK like to work with customers directly so they receive a fair price and the best service.

Check the Minimum Order Quantity (MOQ)

The manufacturer does not have any problem in small-batch production but the problem is raw material availability. CNC machining manufacturer purchases raw material from the supplier who has Minimum Order Quantity (MOQ) depending upon the material. For example, to buy the 316 stainless steel the MOQ is 5 tons, for the aluminum the usual minimum order quantity is 500 kg per order.

To check what is minimum order quantity you must send the manufacturer production drawing and specifications for the production parts. While working with the DEK machining and manufacturing company you can check the MOQ for your product by consulting directly with our technical support team.

Customer Testimonials

Always choose the supplier who has testimonials from the customers. These testimonials must be authentic with full customers details.

A Chinese supplier with authentic customers testimonial even if it’s expensive is better than the one that is cheapest but doesn’t have testimonials.

Quality Inspection

It is highly recommended to ask for a quality inspection before your parts are dispatched. If you can not send the inspector then hire a company for the quality checks. Ask for the location from the supplier to send the inspection team if you get a vague answer it means the supplier doesn’t manufacture your parts by itself, he/she buys it from another factory. DEK provides full address with open policy and chance to inspect your Piezas mecanizadas por CNC as you please.

Check the Payment Terms

Checking out the payments terms before ordering from the Chinese manufacturer is an important step in acquiring a CNC service. Most of the Chinese companies offer a 50% down payment and 50% balance before the delivery of your parts. This may also solely depend upon your relationship with your supplier and the nature of the policy they had. So payments terms can vary from supplier to supplier.

What materials do manufacturers usually use to machined parts?

Manufacturers use different types of raw materials to produce machined parts that can be used in different applications in a vast variety of industries. Below mentioned are some of the common raw materials used in manufacturing machined parts:

Acero inoxidable

It is one of the most popular raw materials used in manufacturing machined parts, due to its strength and resistance to corrosion. It can also be welded vacuum-tight. There are many different types of stainless steel used in CNC machining depending upon their properties and the way it is machined. Stainless steel is a versatile material and its price, machinability, and availability depend upon its grades.

Aluminio

Aluminum is lightweight, easy to machine, corrosion-resistant, non-magnetic, and less expensive as compared to other materials. It has become a preferred choice to steel because of its features like cleaning and machining. For great results, aluminum welding must be done by an experienced CNC manufacturer.

Latón

Brass machining is easy, smooth, non-sparking, clean finish, and holds tolerance. It is commonly used in intricate parts with sophisticated features. Brass is not used in semi-conductor products and vacuum applications because it contains zinc and tin. The brass is commonly used in casting parts.

Titanio

Titanium is expensive and very resistant to heat and corrosion. Titanium has the most significant strength to weight ratio as compared to any metal. It is biocompatible and lighter in weight which makes it suitable for a wide variety of medical and aviation tools. The drawback of titanium is that it is difficult to machine and also has a high price. If you required titanium parts, it is best to choose an experienced manufacturer like DEK to make sure you get the finest parts.

Acero

It is one of the most popular metals in CNC machining and is used for its strength and durability. Much like stainless steel, steel is based on grades used for specific purposes. It is easy to wield as compared to other metals. Steel CNC machined parts are used in industries applications, automotive, oil, and gas industry. It is prone to corrosion without heat treatment.

Cobre

Copper is another metal used in precision machining. It is durable, versatile, electrically conductive, and naturally corrosion-resistant. It is a much better electrical conductor when platted but has less tolerance as compared to aluminum.

What are types of surface finishes do manufacturers usually use for machined parts?

There are so many techniques for surface finishing that alter the surface of the metal to turn them into precise parts. These techniques are used for aesthetic reasons and to protect the part from environmental factors. Below mentioned are the types of surface finishing manufacturers use.

Bead Blast

It is used to create a uniform matte (satin) finish and to clear the tool marks that are visible after the machining process.  As the name suggests, the part is blasted with small beads with a pressure gun. This process removes the surface material and leaves a smooth surface.

Óxido negro

This process turned the machined parts into black. It is used for mild corrosion resistance and to minimize light reflection. The firearms industry requires black oxide to reduce the reflection of light.

Burnishing

It creates the mirror finishing and alters the surface hardness. This process is also used to improve corrosion resistance, reduce fatigue failure and surface visual defects, to eliminate surface porosity.

Passivating

It is the process of changing the surface layer of the parts. In this process, parts are dipped in chemical solutions that change the chemical composition of the surface of the part. The term passivating refers to the fact that this process makes the material more passive which means less like to be affected by the environment.

Galvanoplastia

This process is used to coat the machined part with a metal layer through an electrical current. It is used for enhancing surface qualities and its appearance, corrosion, and abrasion resistance. Also helps in improving lubricity, electrical conductivity, and reflectivity.

How can I find the best manufacturing companies who develop CNC machine parts at the cheapest price?

Finding the right company for your CNC machining project with fair pricing can be daunting, But there are certain things you can consider before choosing a perfect manufacturer for machined parts. These are:

Certifications

This can be a good way to find the suitability of the company. ISO certified manufacturer will be a good option for your CNC machining project but it doesn’t ensure the scope of the company’s abilities.

Send requests for quotations to the different suppliers to see who can offer you the best prices with the utmost services. This will save you time help you to choose the economical supplier from China in no time.

What are the most common manufacturing processes for machined parts?

In the CNC machining process several operations have been employed to get the desired results. Three most common processes are turning, drilling and milling. These processes are mechanical and involve cutting tools and abrasive wheels. Machining operations are performed on bars and flats or it can be performed on parts previously made through welding or casting. Some of the common manufacturing processes are mentioned below.

• Fresado
• Girar
• Perforación
• Screw Machining
• Gun Drilling
• Heat Treating
• Mecanizado por descarga eléctrica (EDM)
• SAW
• High-Pressure Hole Drilling
• Plating
• Pintura
• Laser Or Machine Engraving

What are the main types of processes to get machined parts?

The main traditional methods to remove the excess material from the machined parts are turning, drilling and milling. During these processes, the machinist utilizes sharp cutting tools to cut the material from the parts.

Girar

In this process the machinist let the metal moves against the cutting tool by rotating the workpiece on the turning machine. A turning machine helps to remove the material from the part and shapes it by rotating drive which turns the part into the desired form. Normally turning is used for facing, boring, thread cutting, and cut-off processes.

Perforación

This process is used to create the holes in the workpiece and to increase the size of the existing holes. The action is performed using the cylindrical and rotating tool. The tool penetrates the stationary material to create the hole.

Fresado

In this process, a metal part is passed in front of a cylindrical rotating tool with multiple edges known as a milling cutter. CNC machined parts manufacturers effectively use milling to remove the excess materials from the parts.
