Why Does PVC Machining Emit a Pungent Odor?

Yes. Acrylic is one of the few plastics that can achieve a mirror finish directly through cutting. We use single-crystal diamond tools for precision machining, followed by flame polishing or diamond grinding. Surface roughness is consistently controlled within Ra0.4μm, delivering a high-gloss appearance free of scratches or defects, resembling a mirror. No secondary coating is required. For batch production, identical parameters are used to ensure consistent mirror finish quality.

Appearance quality is a core strength. We use a three-stage control process: during machining, sharp tools with high RPM and shallow cuts prevent tool marks and roughness; between processes, all parts are film-wrapped and transferred in individual stations to avoid stacking scratches; before shipping, each piece is inspected under standard light sources against strict criteria for glossy, scratch-free, and blemish-free finishes. Batch consistency is guaranteed by fixed parameters and fixtures, not manual picking.

Scratches on transparent plastic parts mostly occur during handling rather than machining. We isolate processes to prevent damage: protective films are applied throughout, independent trays prevent stacking between stations, and dedicated fixtures ensure proper positioning. Final inspection is performed under standard light boxes to check each unit's appearance. We guarantee a high-gloss, scratch-free, and flawless finish, not just "imperceptible" defects.

We focus on volume production with a standard MOQ of 100 units. Unit pricing for plastic parts is highly volume-sensitive—raw materials are purchased in full sheets or bars, so material waste and setup time cannot be amortized below 100 units. Prices drop significantly above 100 units, with a standard lead time of 15-25 days for batch orders.

Acrylic is more transparent, reaching up to 92% light transmission; when polished, it resembles optical glass and resists yellowing outdoors. Clear PVC looks similar after polishing but is less expensive and inherently flame-retardant (UL94 V-0), making it suitable for machine windows or protective shields that do not require the highest optical clarity.
