Chengdu Chongqing Economic Circle Surface Finishing Exhibition

Chengdu-Chongqing Economic Circle Surface Finishing Exhibition (成渝经济圈表面处理展览会 / 成渝经济圈表面工程博览会, CCSEE)

A regional surface-engineering / surface-finishing trade exhibition for the Chengdu-Chongqing (Chengyu) economic circle, covering electroplating and electrochemical treatment (metal/plastic plating, anodising, conversion coatings, electrophoresis), painting and coating (equipment, paints, powder/UV coatings, painting robots), vacuum coating / PVD, surface finishing (grinding, polishing, shot blasting, deburring, rust removal), analysis and measurement, and environmental safety (wastewater, VOCs, hazardous-chemical handling) plus plating-park engineering services.

Organisers. Chengdu Surface Engineering Industry Association (成都表面工程行业协会) with Chongqing Surface Engineering Association (重庆表面工程协会) and Chongqing Surface Engineering Technology Society (重庆表面工程技术学会); also joined by 重庆市电镀行业协会, 重庆市涂料涂装行业协会 and 成都涂料行业协会. Contractor: Chengdu Xinzhonglian Exhibition Co., Ltd (成都新中联展览有限公司).

Venue. Chengdu Century City New International Convention & Exhibition Center (成都世纪城新国际会展中心), No. 198 Shijicheng Road, Wuhou District, Chengdu, Sichuan. The series was designed to alternate between the two cities ("from 2021, odd years in Chongqing, even years in Chengdu").

Recent editions.

• 2nd edition - 5-7 June 2024, Chengdu Century City New International Convention & Exhibition Center, co-located with the 2024 Chengdu-Chongqing dual-use (military/civil) equipment surface-treatment technology conference, a supply-and-demand matchmaking meeting and 20+ forums. (An earlier announcement had placed this edition in the 28-30 March 2024 slot; that was superseded - the co-located CDEPE 2024 was itself postponed from 28-30 March.)
• 2025 edition - 1-3 April 2025, same venue, held alongside CDEPE 2025 (Chengdu International Environmental Protection Expo, 1-3 April 2025, same venue), the 2nd Chengdu-Chongqing dual-use equipment surface-treatment technology conference and the association's 7th 4th council and members meeting.
• 2026 - the series' next instalment ran as the "2026 3rd Military/Civil Dual-Use Heat Treatment & Surface Engineering Technology Innovation Conference" (19-21 August 2026) with an on-site exhibition zone of 45 exhibiting companies, at the Qiyi Shiwai Taoyuan Hotel, Xindu, Chengdu - i.e. no standalone exhibition at the convention centre that year.

No next standalone-edition dates are published. The association's dedicated expo subsite (the previous websiteUrl www.cdbmgc.com/expo/) has been removed and now returns HTTP 404 on every path, so websiteUrl was changed to the association's live site. The expo's own former domain www.sfecd.com, which the organisers listed as the show website, has been lost and repurposed - it now serves unrelated freight-forwarding SEO spam - and is therefore unusable. The organiser itself remains active (see the August 2026 conference above), so this is recorded as a between-editions renewal, not a closure; the dates shown are the last confirmed edition of the exhibition and no future dates have been invented.
