Hi everyone, we are a factory specialized in the production of rapid prototype parts with more than 10 years. We provide fast, realistic and practical parts to many engineers in the stage of products designing. These parts can be used to verify whether the design of the product structure is reasonable, or also can be used for marketing promotion in advance, or directly end used. We have certificate of ISO9001, CMM and fully complete inspected equipments, you can rest assured of our quality.
Today, we will show you a product part made of PMMA material and produced by CNC machining. PMMA is also called acrylic too, it is a transparent plastic material with outstanding strength, stiffness and optical clarity. PMMA sheet is easy to machine, it has superior weathering properties compared to other transparent plastics. The materials is used in various industries, such as medical filed, automotive, lighting, exhibition, and etc.
The contour of the product is processed by CNC machines, then surface will be manual ground and polished, which needs to be carried out for many times, and finally it presents a crystal clear and lifelike product effect. As we already known, the acrylic has great optical clarity, however, after machining, the surface is with a lot of tooling marks, and becomes frosted. If we want to achieve the transparent appearance, we need to find methods that to remove the frosted surface.
At Huachen factory, we have very experienced craftsmen to do sanding and polishing. First, we shall use a very rough 240 matched sandpaper to remove the CNC tooling marks, then 400, then 600, then 800 sandpaper will be used to finish the sand polishing work. After that, we will use finer sandpapers such as 1000 and 1500 to polish the acrylic, then use polishing wax and burnishing oil to high polish products, after the whole process, you will receive a fully transparent PMMA part.
Huachen has been doing optical clear acrylic production for more than 10 years and we’ve achieved a lot of rich experience in the past 10 years. We cooperated with a variety of companies to produce lights of cars and illuminating equipments. If you have any PMMA projects, please feel free to contact us, or log in our website www.prototypingparts.com to know more more about the product introduction of various CNC machining products, it can help you find your target products faster, we are happy to serve you, thank you for your time!
