Diamond polishing machine is a semi-automatic mechanical equipment mainly used for precision polishing processing of materials such as acrylic, crystal, sapphire substrates, etc. This device achieves surface precision cutting through diamond cutting tools, which can replace traditional cloth wheel polishing and flame polishing processes. A single device can save 10-20 traditional manual labor.

Acrylic (PMMA) has become a commonly used material in advertising production, home decoration, industrial accessories, and other fields due to its good transparency, strong toughness, and easy processing. To transform an acrylic sheet into various finished products, mature processing techniques are indispensable. Among them, cutting, carving, and bending are the three most widely used mainstream processes, each with its unique technical points and applicable scenarios.

Surface effect: The spray painting process can achieve up to 6 color gradients, comparable to stainless steel wire drawing effect, and with higher color saturation.
Installation convenience: The lightweight acrylic board (only 1mm) is paired with double-sided tape or track type installation, greatly reducing installation difficulty.
Environmental attributes: Alternative material selection reduces metal waste, in line with the current trend of green production.

PMMA has a certain degree of water absorption, with a water absorption rate of 0.3-0.4%, while injection molding requires a temperature below 0.1%, usually 0.04%. The presence of moisture causes bubbles, air streaks, and reduced transparency in the melt. So it needs to be dried. Dry at a temperature of 80-90 ℃ for at least 3 hours. Recycled materials can be used up to 100% in some cases, but the actual amount depends on quality requirements, usually exceeding 30%. Recycled materials should avoid contamination, otherwise it will affect transparency and the properties of the finished product.
