Product Introduction

We specialize in providing industry-leading mirror finishing services for metal surfaces. We utilize advanced precision polishing and ultra-fine grinding technologies to give your products a flawless, mirror-like finish, reminiscent of works of art. Widely used in medical devices, food processing machinery, high-end home appliances, automotive parts, and semiconductor equipment, our services significantly enhance product corrosion resistance, cleanliness, and aesthetic value, helping your brand shine in the global market.

Product Description: What is Mirror Finishing?

Mirror finishing is an ultra-high-precision surface treatment process that uses a series of physical or chemical methods to achieve an extremely smooth, mirror-like surface finish. Surface roughness (Ra) values ​​can reach Ra ≤ 0.01 μm, resulting in extremely high reflectivity and clear, distortion-free images. This is achieved not only for aesthetic reasons but also to meet functional requirements such as high cleanliness standards, reduced friction coefficients, and enhanced anti-adhesion and corrosion resistance.

FAQ

Q1: What design file formats do you handle?

A: We accept nearly all major 3D formats, including STEP (.stp), IGES (.igs), SolidWorks (.sldprt), and Parasolid (.x_t), as well as 2D drawing formats such as PDF and DXF. To ensure accuracy, we strongly recommend that you also provide standard engineering drawings with complete dimensions, tolerances, and technical requirements.

Q2: How long does it take from receiving your documents to receiving a quote?

A: For most inquiries, we offer a quick quote within 24 hours. For particularly complex parts, we may require additional time for process review, but we will communicate this promptly.

Q3: What is your minimum order quantity (MOQ)?

A: We do not have a strict MOQ. We support single-piece prototypes and small trial runs, as well as large-volume production orders. For small-volume orders, pricing is primarily based on processing time and material costs.

Q4: How do you guarantee part quality?

A: We conduct full-process quality inspections. From first article inspection (FAI) to in-process spot checks, we use precision inspection equipment such as coordinate measuring machines (CMMs), 2D image measuring machines, calipers, and micrometers to perform 100% inspection of critical dimensions and provide comprehensive inspection reports.

Q5: What is a typical production cycle?

A: Production cycle time depends on part complexity and order quantity. Typically, prototypes take 3-7 business days, while production runs require an assessment based on specific quantities. We will provide you with an accurate production and delivery schedule when quoting. Q6: Do you offer global logistics services?

A: Yes, we can provide reliable and efficient logistics and delivery services to our customers worldwide.
