From a service workshop in 1999 to a global automatic door manufacturer
For over 25 years, DoorDynamic has been engineering automatic door systems at our factory in Guangzhou, China. Our CE-certified sliding door operators are built on Dunkermotoren drive technology from Germany, and every heavy-duty entrance solution is fully customized to project requirements. DoorDynamic operators have been specified for landmark projects including The Venetian Macao, ZARA South Africa, Huawei, and SMIC.
From a service workshop to an independent manufacturer
DoorDynamic was founded in 1999 in Guangzhou, China, as an agency and maintenance operation for international automatic door brands. Our core business in those early years was straightforward: service long-term clients, supply out-of-warranty spare parts, and solve the problems the original equipment manufacturers were too slow to solve.
What we discovered changed the trajectory of the company. At the time, the original brands paid little attention to aftermarket parts and service — and what they did offer came at a steep price. We spent our first decade optimizing the supply chain, raising our parts quality to match the original brands — and eventually to exceed it — and establishing our own automatic door testing laboratory to strengthen after-sales service and quality control. Those ten years took DoorDynamic from agency to in-house R&D, then to OEM manufacturing, and finally to our own independent brand.
That foundation — service expertise, parts quality, and a deep understanding of how doors fail in real buildings — is what DoorDynamic is built on today. Read the milestones below for the full story.
From industry pioneer to global leader in intelligent manufacturing
Four phases have shaped DoorDynamic — agency and maintenance, in-house R&D, OEM for brands and export expansion, and independent brand. Together they explain why we can credibly serve both the original equipment manufacturers and the facilities that maintain their doors.
-
1999Founded as an automatic door agency and maintenance specialist. DoorDynamic began as an authorized agent and maintenance provider for a leading international automatic door brand in southern China. Our core business was serving long-term clients and supplying out-of-warranty spare parts — where we discovered the aftermarket opportunity that would define the company.
-
2006In-house R&D and customized solutions launched. We began developing our own products, launching the ES200 series and producing more than 20,000 wheels. This built our custom-development and mass-production capabilities, and we established an automatic door testing lab to strengthen quality control and after-sales service.
-
2008Business model validated. Demand from long-term service clients confirmed what we had believed all along: facilities want a single supplier who understands both the brand-name equipment and the aftermarket parts needed to keep it running.
-
2016OEM for brands and export expansion. We partnered with Germany's Dunkermotoren as an authorized distributor, integrating German technology into our own products. In cooperation with brand agents, we began exporting — the start of our international reach.
-
2022Three-panel telescopic curved sliding door. We released a three-panel telescopic curved sliding door — a complex non-standard configuration combining telescopic tracking with a curved profile, engineered in-house for landmark architectural specifications.
-
2023500 kg heavy-duty door motor released. We launched a 500 kg-class heavy-duty motor for high-traffic and high-wind-pressure entrances.
-
2024Independent DoorDynamic brand launched. With our industry reputation established, we undertook secondary OEM for leading Chinese brands and launched the independent DoorDynamic brand — demonstrating the market for high-quality automatic doors. Products now ship to Europe and the Gulf, with components and doors specified for Huawei, SMIC, P&O Cruises, Louis Vuitton, Gucci, Swire, and The Venetian Macao.
-
2024CE certification across the product line. The ES200, ES200e, SL190, SL100, and SLH250 sliding door operators passed CE conformity assessment under the EMC Directive 2014/30/EU (certificate TBC-C-202407-0111-11) and the Low Voltage Directive 2014/35/EU (certificate TBC-C-202407-0111-12) — third-party verified electromagnetic compatibility and electrical safety.
-
2025ED250 swing-door operator released. We completed the product line with the ED250 swing-door operator, supporting telescopic, curved, and other door types through the same Dunkermotoren-powered platform.
What we manufacture
DoorDynamic produces the components that keep automatic doors cycling reliably — from the motor that drives the panel to the sensor that detects a child running through.
ES200 sliding door operator
Our flagship sliding-door platform, in continuous production since 2006. The ES200 is the platform that built our reputation with Dorma-compatible installations across China.
Dunkermotoren drive systems
Every DoorDynamic operator is fitted as standard with German Dunkermotoren motors — surging power, fluid low-noise operation, and long service life. We are an authorized Dunkermotoren distributor, moving approximately 3,000 motors per year.
ED250 swing-door operator
Released in 2025 to complete our product line. Compatible with linear, telescopic, curved, and other door types — and designed to integrate with sensors, access control, and fire-safety systems.
500 kg heavy-duty door motor
Built in 2023 for high-traffic entrances and high-wind-pressure conditions. Extends our range into applications where standard residential and light-commercial operators are insufficient.
Three-panel telescopic curved sliding door
Released in 2022 — telescopic tracking and a curved profile combined in one custom build, engineered for architectural specifications where standard configurations cannot meet the brief.
OEM for top Chinese and international brands
OEM manufacturing for leading Chinese brands and customized solutions for international-brand agents. DoorDynamic supplies genuine OEM, certified compatible alternatives, and full custom engineering — all from our testing-laboratory-equipped factory in Guangzhou, China.
Brands we cover
DoorDynamic produces OEM-quality replacement components and fully compatible alternatives for the world's leading automatic door systems. All brand names are the property of their respective owners and are used solely to indicate compatibility.

Leo Lo
Leo leads DoorDynamic's growth across the Gulf Cooperation Council region and Europe. He joined in 2021 to open the GCC distribution channel and has built DoorDynamic's presence across the UAE, Saudi Arabia, Qatar, and Bahrain through a network of regional distributors serving hospitality, healthcare, retail, and commercial real estate clients.
Leo's career started in European markets: before joining DoorDynamic, he spent years selling automatic door systems across the EU — developing distributor accounts and learning how entrance specifications work in Europe. That experience now drives DoorDynamic's European growth directly: alongside his GCC leadership, Leo personally supports DoorDynamic's distributors and end customers across Europe, applying the same distributor-development and account-support playbook that built his Gulf network. DoorDynamic's expanding European customer base is his contribution, too. Trilingual in Mandarin, English, and Arabic, Leo is the reason DoorDynamic can serve GCC facility teams in three languages — quoting in English, confirming specs in Mandarin with the factory, and closing deals in Arabic with regional distributors. He is also the voice behind much of our external content, including his writing on niche B2B e-commerce at Indie Hackers.
Where we manufacture and ship
DoorDynamic manufactures from our testing-laboratory-equipped factory in Guangzhou, China, and operates a commercial presence from our Guangzhou office. DoorDynamic-brand products ship to Europe and the Gulf; GCC sales are led by Leo Lo through the regional distributor network he has built since 2012.
