As a specialized Kovar (4J29) package shell manufacturer, we understand that the integrity of electronic systems depends entirely on the reliability of the hermetic seal. Kovar, a controlled expansion alloy composed of iron, nickel, and cobalt, is the gold standard for applications where metal-to-glass or metal-to-ceramic seals are required.
In the context of New Zealand’s industrial landscape—ranging from the burgeoning aerospace industry centered in the Mahia Peninsula to high-precision medical device manufacturing in Auckland—the demand for materials that can withstand extreme pressure differentials and temperature fluctuations is at an all-time high.
Founded in November 2014, Xinyunyang has adhered to its initial intention of industry, sticking to the business principles of Integrity, Innovation, Cooperation, and Sharing. We focus on Kovar precision processing technology as our core competitiveness.
We deeply cultivate the fields of semiconductors, optical communications, aerospace, medical devices, and new energy, providing miniaturized, customized, and high-reliability metal packaging solutions to global customers, including significant support for New Zealand’s technical infrastructure.

Driven by ISO 9001 intelligent schedulingNew Zealand has rapidly emerged as a global hub for small satellite launches. Our Kovar 4J29 shells provide the essential hermetic protection needed for delicate sensors during high-vibration launches and the extreme thermal cycling of orbit. We support local NZ aerospace startups with custom prototypes and rapid iteration.
In Auckland’s world-class medical device sector, biocompatibility and sealing are non-negotiable. Our Kovar components are used in implantable electronic devices and diagnostic equipment, ensuring moisture-free environments for long-term device stability.
New Zealand’s unique geographical position requires advanced marine research. Our Kovar packaging solutions are critical for deep-sea acoustic sensors and underwater communication systems, where pressure-resistant hermetic sealing is the only barrier against the ocean.
As we look toward 2025 and beyond, the roadmap for Kovar manufacturing is evolving. We are currently integrating Artificial Intelligence (AI) into our machining processes to predict tool wear when working with tough alloys like 4J29, ensuring even tighter tolerances for our New Zealand clients.
Elevate your New Zealand-based engineering projects with precision-machined Kovar shells.
