Sandblasting |
Different sands are used to spray the surface of the parts, the surface requirements of the products are different, the sands used are also different, and the prices are also different. |

Polishing |
Ranging from Ra 0.8~Ra0.1, polishing processes use an abrasive material to rub the part’s surface to make the shine more or less shiny, depending on your requirements. |

Hard Anodizing |
That is coating thickness, and normal anodizing will probably be less than 10μm. Hard anodizing is normally above 20μm. The higher the value, the higher the wear resistance and the higher the cost. |

A customer’s words have a more substantial impact than a company’s claims – and see what our satisfied customers have said regarding how we fulfilled their requirements.
1. How do you control the quality of surface treatment?
In addition to conventional surface treatments, there are a variety of special surface treatments. We have a full-time SQE to follow up and control each process in the surface treatment factory. After returning to our workshop, the product appearance will be 100% inspected.
2. What surface treatment you can do?
According to customer requirements, according to different effects and materials, we provide customers with many kinds of surface treatments, such as oxidation, sandblasting, polishing, electroplating, powder spraying, baking paint, PVD, laser engraving, blackening, wire drawing, heat treatment, etching, etc. In addition to the above conventional surface treatments, there are also a variety of special surface treatments. Please refer to the attached picture.
3. How do you package it?
Commonly used packaging methods include wrapping in pearl cotton or white paper, placing in bubble bags, PE bags, blister boxes, blister trays, etc. Please see the attachment. VMT can also customize packaging according to needs
4. Are your prices competitive?
We have 100 pieces of equipment and 6 engineers to optimize the structure and choose the most appropriate process to reduce production costs.
5. How long have you been in this industry?
Brief introduction: 30 years in the machining industry. Founded VMT in 2011, Sam Xie has successfully completed projects for clients, including major public companies, and has served more than 600 clients.
