Driven by tightening environmental policies and industrial upgrading, the relocation of surface treatment enterprises in the Pearl River Delta region into industrial parks has transitioned from policy guidance to full-scale implementation. This article reviews the policy requirements, current progress, and major industrial park distribution for electroplating and surface treatment enterprises in Guangdong. Drawing on practical cases from Huizhou Boluo, Foshan Jun'an, and Zhaoqing Gaoyao, it summarizes pragmatic experience in site selection assessment, cost estimation, production transition, and policy utilization, providing a reference for surface treatment enterprises facing relocation decisions.

To provide clients with a more intuitive understanding of the actual operational performance of fully automatic oxidation production lines, Dingli Technology recently organized a group of client representatives from Guangdong and surrounding provinces to visit a partner factory in Dongguan for an on-site inspection and observation tour. During the visit, clients observed a continuously operating fully automatic oxidation production line and received detailed briefings on equipment layout, process flow, control system operation, and routine maintenance. Participating clients generally reported that the observation tour gave them a clearer understanding of the actual production capacity, automation level, and operational stability of fully automatic oxidation production lines.

Aluminum profiles and steel parts are the two most common metal substrates in industrial manufacturing, yet they follow fundamentally different logics in surface treatment process selection. For aluminum profiles, anodizing is almost the only choice that combines technical feasibility with economic viability, due to the natural oxide film on the surface and the difficulty of electroplating. For steel parts, electroplating has become the mainstream method for corrosion protection and functional enhancement, thanks to its mature technology and wide range of coating options. This article compares substrate characteristics, process principles, performance differences, and cost considerations, providing a reference for manufacturing enterprises in making process decisions between oxidation and electroplating.

Recently, Shenzhen Dingli Environmental Technology Co., Ltd. (hereinafter referred to as "Dingli Technology") completed the installation and commissioning of an electroplating production line in Jiangsu Province and officially delivered it to the client for trial operation. The client is a local automotive parts manufacturer, and the production line is primarily used for zinc plating on their automotive structural parts and fasteners. The project, from design and manufacturing to on-site installation and commissioning, lasted approximately three months and has now passed the client’s preliminary acceptance inspection, with stable equipment operation and all process parameters meeting design requirements.

With the formal implementation of the “Regulations on Ecological and Environmental Protection Inspections” and the promulgation of the “Ecological Environment Code,” environmental protection inspections have transitioned from campaign-style enforcement to a normalized, institutionalized legal framework. For small and medium-sized enterprises with limited financial and technical resources, the key is not to passively cope with inspections but to proactively establish a compliance management system. This article analyzes policy trends, common compliance risks, and pathways for building a robust compliance framework, offering practical and actionable guidance for SMEs in the surface treatment industry.

In the first quarter of 2026, Dingli Technology experienced significant year-on-year growth in deliveries of oxidation production line equipment, primarily driven by sustained demand for capacity expansion and production line upgrades from downstream industries including aluminum profile processing, new energy vehicle components, consumer electronics, and precision hardware. Leveraging its full-process service capabilities and technological innovation, the company accelerated order conversion and completed delivery and acceptance for multiple projects. Dingli Technology will continue to focus on technological upgrades and energy-saving optimization for fully automatic oxidation and electroplating production line equipment, aiming to maintain steady delivery growth throughout the year.
