Custom CNC Machining Parts Application Field

New Energy Industry

YIJIN Hardware as one of the top CNC machining parts manufacturers in China will provide you with a one-stop solution for your custom new energy parts.

Shipping Industry

Shipping is the largest transportation method that we can achieve in single transportation so far, which also highlights the importance of shipping.

Aerospace Industry

Aircraft parts production requirements are strict, and the parts produced need to have strong corrosion resistance. In addition to oxidation resistance, it should also ensure lightweight and high-strength impact resistance.

Auto Industry

Shipping is the largest transportation method that we can achieve in single transportation so far, which also highlights the importance of shipping.

Rapid Prototyping

First of all, 3D printing is a material increase technology, and CNC Rapid Prototyping is a material reduction technology, so they are very different in materials.

Consumer Products

As we all know, CNC machining centers are suitable for machining parts that are complex, have many procedures, are demanding, require multiple types of ordinary machine tools and many tool fixtures, and can only be processed after multiple clamping and adjustments.

Medical Industry

Medical care is very important to human life. As a
customized machining parts supplier, YIJIN Hardware has been committed to providing the best custom medical components for the medical industry.

Semiconductor Industry

Good quality, high-cost performance, favorable price, and a full set of pre-sales and after-sales services are the recognition of customers for the semiconductor parts we produce. Currently, we serve 7 semiconductor manufacturers.

Mold Making​

CNC machining technology is mainly a technology adopted under digital information, with the characteristics of digitalization and automation.

Machinable CNC Metal Materials

CNC Custom Machining Parts Surface Treatment Types

Type II (MIL-A-8625, Type II) creates a corrosion-resistant finish. Parts can be anodized in different colors—clear, black, red, and gold are most common—and is usually associated with aluminum. Type III (MIL-A-8625, Type III, Class 1/2 “hardcoat”) is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.

A hard coat anodize process that embeds PTFE to create a self-lubricating, dry contact surface with Type 3 hard coat’s protective properties. This finish can be used on aluminum alloys or titanium and increases the service life of the product. This finish conforms to the AMS-2482 Type 1 Hard Coat Anodizing with Teflon (Non-Dyed).

A surface finish for titanium per AMS-2488 Type 2 specification. Also called Tiodize, this finish increases fatigue strength and the wear resistance of a part. Titanium anodized parts are common in aerospace and medical device manufacturing. Non-pigmented titanium anodize finishes will dull shine.

Also known as buffing, a process of rubbing the surface of parts or utilizing a chemical action to produce a smooth and shiny surface, make the surface get significant specular reflection or reduce diffuse reflection in some materials.

Refers to an altering surface finishing process, spraying paint, pigment, or color to a solid surface as a colored protective layer, and can be done on metal or non-metal CNC machined components of any shapes, usually applied on aluminum, stainless steel and steel alloy parts. The purpose is to improve aesthetic appearance and prevent corrosion or oxidation.

A common chemical surface treatment method for steel and stainless steel, to remove ferrous contaminants or use a light coat of protective material to create a shell for enhancing the corrosion resistance or reducing the chemical reactivity.

A process of using an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode, to change the properties of the machining metal surface or build up thickness for undersized parts.

Provides corrosion resistance and good conductivity properties. Can be used as a base for paint. Can leave surface yellow/gold. Adds very little thickness, about 0.00001”-0.00004”. Chem film will conform to MIL-DTL-5541, TYPE I/II.

This is a process where powdered paint is sprayed onto a part that is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic.

Black Oxide: Also known as blackening, gun bluing or hot blackening, a chemical process of forming a black conversion coating on stainless steel, copper and copper based alloys, zinc, powdered metals, silver solder, and ferrous materials, to improve corrosion resistance and minimize light reflection.

Conversion Coating: Also call as chromate conversion, the coating are used for metals converted to a protective layer through the chemical or electrochemical processes, primarily used as a corrosion inhibitor, decorative finish, or to retain electrical conductivity.

Bead blasting/Bead Blast: the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface.

Abrasive Blasting/Sandblasting: the process or operation of propelling a stream of abrasive material composed of high-velocity sand-sizes particles against the metal surface under high pressure with blast equipment like air pressure system, to remove surface contaminants, clean metals or increase a texture, then change the smoothness or roughness of surface.

YIJIN Hardware also provides grinding, linishing, industrial etching, and more custom metal finishing service for presenting the best effect of your part.

CNC Macining refers to a series of processing methods for parts on CNC Macining machine tools. At the same time, CNC Macining is also a method of subtractive manufacturing.

It uses computerized equipment to remove excess material from the blank and uses numerical control machine tools to complete the required tasks. Because CNC machining is a general term for various precision machining such as CNC turning, CNC milling, CNC drilling, etc.

CNC machining can solve the variety of parts, small batches, complex shapes, etc. Through the various precision CNC machining methods just introduced and the problem of high precision.

Since the CNC machining is processed by the computer after the program is written. The precision CNC machining has stable processing quality, high precision, can process complex surfaces, and high processing efficiency.

It is an effective way to realize high-efficiency and automatic processing.

Our CNC machining services range is very wide. 

Including: 5 axis cnc machining services, CNC milling servicesCNC turning machining, CNC Drilling Services, small parts machining, gear machining servic, CNC cutting and Wire EDM services.

YIJIN Hardware’s CNC machining service integrates a number of advanced technologies to simplify the manufacturing process, speed up the mass production of CNC machined parts, and achieve higher precision and precision.

We are proud to produce CNC machined parts with the smallest tolerances and the highest precision. At the same time, we can also use EDM and grinding machines according to customer requirements manufacture precision parts.

The following is our related CNC machining services information.

As a metal manufacturing CNC machining company that YIJIN hardware produces CNC metal parts, customized machining parts according to customer’s requirements.
