New Zealand's unique geographical landscape—ranging from coastal salt-heavy environments to the rugged Southern Alps—demands cooling systems that are both resilient and efficient. As a premier Radiator Plastic Tank Crimping Factory and Supplier, we recognize that the NZ automotive and industrial sectors are shifting toward high-precision aluminum components.
In regions like the Waikato and Canterbury, where agricultural machinery and heavy-duty transport are the backbone of the economy, the demand for reliable radiator plastic water chamber crimping has skyrocketed. Traditional repair methods are being replaced by automated clinching technology that ensures a leak-proof seal between the plastic tank and the aluminum header plate, extending the lifespan of vehicles in harsh Kiwi conditions.
Current trends show a 15% increase in domestic remanufacturing of cooling units to reduce reliance on long-lead international shipping.
Our crimping machines are calibrated to handle thermal expansion coefficients specific to NZ's extreme temperature fluctuations.
Establishing a professional radiator assembly line in New Zealand requires more than just machinery; it requires expertise (E) and experience (E). Our automatic radiator tank crimping machines are designed with AI-integrated sensors that monitor tooth compression force in real-time. This is critical when working with PA66-GF30 (Glass Fiber Reinforced Nylon) tanks commonly found in modern European and Japanese imports across New Zealand.
In the heart of the Bay of Plenty, tractors and harvesters face immense vibration. Our heavy-duty crimping solutions ensure that the radiator core-to-tank bond remains intact during peak harvest seasons, preventing costly downtime for farmers.
The SH1 corridor between Auckland and Christchurch sees heavy freight traffic. Our semi-automatic and full-automatic crimping machines allow fleet maintenance workshops to repair intercoolers and radiators on-site, ensuring NZ’s supply chain stays moving.
NZ’s off-road culture demands radiators that can withstand extreme jolts. The Viktec repair kits and precision pliers we supply are favorites among specialist 4x4 workshops in Queenstown and the West Coast.
While primarily automotive, the same crimping technology is adapted for marine heat exchangers in Auckland’s "City of Sails," utilizing our corrosion-resistant rubber hoses and sealing components.

We are committed to providing high-quality, cost-effective, and innovative solutions that meet the rigorous demands of our global customers, including the specific requirements of the New Zealand market.
Our R&D unit is the cornerstone of our business, conducting detailed research and surveys to improve the performance and durability of our products. This commitment to innovation allows us to design new products with superior functionality, tailored to the specific needs of our clients. Additionally, we actively explore new applications for our cooling solutions, ensuring we remain at the forefront of the industry.
We are proud to be ISO/TS 16949 certified, and our state-of-the-art manufacturing facility is equipped with advanced technologies, including Brazing Furnaces, Fin Machines, and Core Assembly Machines.
As the automotive world moves towards electric vehicles (EVs), the demand for high-efficiency thermal management systems in New Zealand is evolving. However, the existing fleet of internal combustion engine (ICE) vehicles and heavy machinery requires high-quality maintenance tools. Our role as a Radiator Plastic Tank Crimping Factory is to bridge the gap between manufacturing technology and local service requirements.
Our products are widely used in automobile, heavy industry, shipbuilding, sugar processing, packaging, navigation, molds, and other specialized applications. We uphold the highest ethical standards in all aspects of our business and are committed to continuous improvement. Our relentless pursuit of excellence has enabled us to expand our presence globally, making us a trusted partner for businesses throughout New Zealand—from Auckland to Dunedin.
To deliver high-quality and cost-effective cooling solutions that not only meet but exceed customer expectations, while fostering a culture of innovation and sustainability.
To be a global leader in the auto parts industry, recognized for our advanced technologies, outstanding customer service, and environmental stewardship.
