About us

Artisans' handiwork breathes life into molds. Mirror polishing specialists, Koki Polishing Industry Co., Ltd. [A technical group preserving traditional hand polishing] Amid accelerating automation in modern manufacturing, Koki Polishing Industry Co., Ltd. stands as one of the few technical groups steadfastly committed to hand finishing by artisans. We specialize in hand-polishing plastic molds, earning deep trust from diverse clients across industries, including automotive parts manufacturers. Mirror polishing molds isn't merely about making surfaces shine. It's an extremely delicate and painstaking process that determines product quality. Our veteran craftsmen apply their years of accumulated expertise and finely honed senses, meticulously finishing each mold with responsibility.

【Extensive Capabilities and Ultimate Mirror Finishes Down to #14000】 Our strength lies in extensive experience finishing molds for all industries. We offer flexible solutions tailored to customer needs, from #180 paper polishing to the ultimate mirror finish achieved with #14000 grit.

Even for projects deemed "difficult to polish" due to material or shape, our skilled craftsmen select the optimal polishing process, delivering value beyond the blueprint. 【Handling Large Molds up to 3t】 Beyond precision work, we leverage our equipment and space to handle heavy components. We accept delivery and processing of molds up to 3 tons (subject to consultation based on size and shape). If you have a large mold requiring precise polishing but were turned down by other companies due to its weight, please consult with us first. 【Thorough Field-Based Approach: "On-Site Visits for Every New Order"】 What we value most is communication with our customers and a thorough sense of responsibility for the finished product. As an expression of this commitment, we adopt a system where, for new transactions, we always conduct an "on-site visit" as a rule, allowing you to directly confirm the delivered items.

By physically inspecting the mold on-site and making subtle touch-ups and fine adjustments, we ensure we precisely share your ideal "polish." We firmly believe this hands-on, on-site approach prevents post-delivery issues and builds lasting trust. 【Your Partner Supporting Your Challenges】 Koki Polishing Industry Co., Ltd. flexibly accommodates short lead times, including during long holidays and the year-end/New Year period.

We respond with our technical expertise and sincerity to challenges such as "urgent polishing is needed," "high-quality mirror finish is required," or "we want to entrust heavy molds." Please see for yourself the quality of our polishing—a quality that preserves traditional techniques while never forgetting to embrace new challenges.
