The Hot Chamber Die Casting Process
Surface Finish Options for Die Casting Parts
The diecast must have a good surface finish that will promote durability, protection, or aesthetic effect. There are different finishing options you can use for die casting parts. However, choices are based on the size of the cast parts and the alloy you are using.
Painting
Painting is the most common surface finishing technique ideal for many materials. It can be for further protection or aesthetic purpose.
The process involves applying lacquers, paints, or enamel with special consideration for the metal used. Before the addition, clean the surface of the metal to remove impurities such as oil (this also helps in adhesion), add an underlying paint (primer), and the primary paint.

Which Surface Finishes Can You Apply After Die Casting Parts?
Some of the surface finishes which you can apply after dying casting parts include:
1. Anodizing: it is a protective coating that is non-conductive and seals the die casting parts.it is available in several colors such as black, blue, and red and it is quite affordable in forming a resistance to corrosion and durability.
2. Paint: it is a natural coating that uses powder coat paint on your die casting parts.
When the paint is applied to metal surfaces that are pre-treated or non-treated, you obtain die casting parts that have a great look and are customizable.

Quality Control Measures for Aluminum Die Casting
Other Alloys Used in Die Casting
Magnesium Die Casting
It has a great weight-to-strength ratio and can be machined easily.
Magnesium die casting is also able to reduce the corrosion of materials used in zinc die casting and remove harmful repercussions of impurities.
The main problem with magnesium diecasting is that it corrodes fast, and this is hard to control.
The most effective way of reducing corrosion is to use surface coating modification on the magnesium die casting parts.
Magnesium die casting also has the disadvantage of requiring a lot of post-production processing.
Its overall production cost is also higher as compared to aluminum or zinc die casting.

CNC Custom Highly Precision Metal Parts
What is High Precision Parts?
High precision part or precision machining can always be seen when it comes to designing, manufacturing machines, components, tools and etc. So, what exactly are they, why do we need them for the manufacturing project.
High precision components or precision machining are referring to parts that have tolerances to single digit micrometers. A machine is made up of many large and small components, and if all of the parts do not have specific sizes, they cannot fit together tightly and function properly. In order for the machine to fit together tightly and have a consistent performance, machine manufacturers will find a precision part supplier that can provide them with the particular part they need.

How To Draw Cnc Machined Part Drawing？
Analyze Parts And Determine Expressions
Before drawing, you must first understand the name, function of the part, its position in the machine or part, and the connection relationship of the assembly. Under the premise of clarifying the structural shape of the part, in combination with its working position and machining position, determine which one of the four types of typical parts described above (both bushings, disks, forks and boxes), and then according to Expression characteristics of similar parts, determine the appropriate expression scheme.

The Process of Precision CNC Parts
Applications of CNC Machining:
CNC machining is a versatile and cost-effective manufacturing process. This process is compatible with a huge range of materials. As such, CNC machining helps across a diverse array of industries for a variety of applications. Manufacturers and machinists use this process in various ways. This includes direct manufacturing process, indirect manufacturing process, or in conjunction with other processes.
As with any manufacturing process, the unique advantages of CNC machining inform the kind of applications for which it can be used. However, the benefits of CNC are desirable in virtually any industry. They are suitable for many parts and products. Since CNC machines can process almost any type of material, their applications are near limitless.
From direct part production to rapid prototyping, this article looks at the various robust applications of CNC machining. Let’s get straight to it!

Industries That Use CNC Machining
Consumer Electronics
CNC machining also helps in the prototyping and production of consumer electronics. These electronics include laptops, smartphones, and many others. The chassis of an Apple MacBook, for example, comes from the CNC machining of extruded aluminum and then anodized.
In the electronics industry, CNC machining helps to create PCBs, housings, jigs, fixtures, and other components.

Custom Highly Precision Injection Moulding Parts
Precision mold parts performance requirements
1. Strength and toughness
High precision mold and tool components often work under harsh condition. Some usually bear a large impact load, resulting in brittle fracture. Thus, precision molds should have high strength and toughness. It’s to prevent mold components from breaking suddenly during working. And the toughness of the mold and tool mainly depends on the carbon content, grain size, and microstructure of the material.
2. Fatigue fracture performance
The fatigue fracture always happens when the high precision plastic injection mold parts are working. It’s because of the long-term effects of cyclic stress. The forms include multiple impact with small energy, stretch, contact, and bending fatigue frature. In general, this property of custom molding and tooling depends on these factors. Like its strength, toughness, hardness, and inclusions content in the material.

Precision Sheet Metal And Stamping Parts
Types Of Sheet Metal Stamping Processes
There are a lot of different metal stamping processes. Each of them is quite basic but as a combination, they can yield almost any geometry possible. Here are the most widespread sheet metal stamping processes.
Blanking is often the first operation to be carried out among the stamping processes. It requires a stamping press with a sharp punch. The metal sheets are usually supplied in large sizes such as 3×1,5 m. The majority of parts are not as big, so you’ll need to cut off the section of the sheet for your part, and it would be ideal to get the desired contour of the final part right here. So, blanking is applied to get the contour you need. Note that there are other ways to make a metal sheet blank such as laser cutting, plasma cutting or water jet cutting.

CNC Machining Clear Anodised Aluminum Parts
Types Of Aluminum Machining!
The manufacturing industry aluminum can barely cope without aluminum. Below are a few machining types with high speeds used in the industry.
1. Machined Aluminum Prototype
Machined aluminum prototypes are mainly products of a variety of alloys. The commonly used alloy is 6061-T6, covering transportation, aerospace, electronics, and military industries.
Aluminum alloys have high strength and low density. Most time, Aluminum CNC machining has a high tolerance to control as much as 0.01MM. Quality and unique aluminum equipment can be manufactured via CNC. The perfect choice for this process is CNC Milling, and it has high accuracy and precision in milling aluminum.
Prototype manufacturing in aluminum takes several processes from aluminum blocks. Wide range of technologies and machines come up with the best tool design for each equipment made.
Designers and manufacturers tend to launch their products In the shortest possible time frame to save cost. A sample close to the original will be manufactured.
