Shiyinwall Auto Parts Company Investment Expansion

On the morning of March 8, City Wall Automotive Parts Co., Ltd. officially announced the launch of its "Waler Industrial Park" auto parts production project, which is set to be established in Xiongjiawan Village, Hanjiang Street, Zhangwan District. The project marks a significant investment of 120 million RMB by the company, signaling a major step forward in its expansion strategy. According to the latest reports, the project spans a total area of 80 acres and will be developed in two distinct phases. The first phase is expected to occupy 37 acres of land, with a total investment of 50 million yuan. This stage will focus on manufacturing key automotive components such as intake and exhaust systems, as well as muffler systems. Once fully operational, the facility is projected to generate an annual sales revenue of 120 million yuan. The second phase of the project will utilize 43 acres of land, with an additional investment of 70 million yuan. This phase will introduce advanced foreign technology to produce automobile sunroof parts, specifically designed to complement Dongfeng's trucks and passenger vehicles. Upon completion, this part of the project is anticipated to bring in an annual sales income of 180 million yuan. Together, the two phases are scheduled to be completed within a two-year timeframe. The project not only strengthens the local industrial base but also enhances the region’s position in the automotive supply chain. With a strong focus on innovation and quality, City Wall Automotive Parts aims to become a leading player in the industry, contributing to both economic growth and technological advancement in the area.

Technical details of CNC plastic machining

The machines used in CNC plastic machining are milling machines with 3 axes with digital control. They are automated and controlled by a computer that determines the path of the cutter according to the 3D file to be created. In plastic CNC machining, no molds are needed, thus reducing the costs and startup times. The machines can design several identical copies and thus obtain the same quality for all copies of a lot, but few economies of scale are possible. The wide choice of thermoplastics and metals allows parts to be obtained with the desired physical properties.

Plastic CNC turning

Hony CNC turning involves holding a plastic piece in place on a lathe, which is then rotated against the cutting tool in a spinning or turning motion. There are many different forms of CNC turning, each with its own unique purposes and results. For instance, straight or cylindrical CNC turning is best for large cuts, while taper CNC turning creates a distinct cone-like shape.

Specific guidelines for creating plastic parts with CNC turning machines include:

• Minimizing rubbing by making sure cutting edges have a negative back rake
• Using generous relief angles for cutting edges
• Polishing top surfaces to help reduce material buildup and yield a better surfact finish
• Using fine C-2 grade carbide inserts

For rough cuts, we recommend using a feed rate of 0.015 IPR. For more precise final cuts, we recommend a feed rate of 0.005 IPR. Product teams should also know that clearance angles, rake angles, and side angles will change depending on the material used in CNC turning.

Plastic CNC milling

HONY CNC milling is a computer-controlled milling process that uses a cylindrical rotating tool, called a milling cutter, to remove material from a solid workpiece and reveal a finished part. CNC milling machined can be broken down into two broad categories - 3-axis mills and multi-axis mills. 3-axis mills move the cutting tool or the workpiece along three linear axes - left to right, back and forth, up and down - and are best for creating simpler designs. Multi-axis mills, including milling machines with four axes or more, are best for creating plastic parts with complicated geometries.

Specific guidelines for creating plastic parts via CNC milling include:

• Using carbon tooling if you're machining with a thermoplastic that has been reinforced with glass or carbon fibers
• Using clamps to achieve higher spindle speeds

Creating rounded internal cornera and pockets with end mills to mitigate stress concentration

Plastic CNC drilling

HONY CNC drilling involves using a drill bit to drill holes into a plastic block. A spindle, which secures the block and CNC drill, lowers onto the block and then drills the appropriately-sized holes. There are multiple kinds of drill presses you can use with a CNC drilling machine, including upright, bench, and radial CNC drill presses.

When you're creating plastic components via CNC drilling, it`s critical that you keep CNC drill bits sharp. Dull or incorrectly shaped drills can put too much stress on the part, causing tooling problems and performance issues. For most thermoplastics,we recommend using a 90 to 118° drill bit with a 9 to 15° lip angle. If you`re drilling with acrylic, you should use a 0° rake.

The ejection of the CNC drill is also essential as poor chip ejection can cause friction and build heat. Since CNC drilling generates more heat than any other CNC machining process, heat reduction is critical to minimizing stress and damage. To safely remove a CNC drill without damaging the part, try to make sure the drilling depth isn`t more than three or four times the drill diameter and reduce the feed rate when the drill has almost exited the material.
