How Does HMPUR Adhesive Work in TWS Earbud Assembly?
HMPUR sets on cooling, then crosslinks with ambient moisture. HHD 6002 bonds PC and ABS earbud shells; HHD 6009 adds elongation for metal and glass...
• SECT_01 // ENGINEERING IMPACT
Driving measurable improvements in yield, throughput, and reliability.
Typical first-pass yield we engineer toward on automated micro-assembly. In tight builds like lav-mic acoustic sealing, overflow control on UV-delay dispensing — and micro-welding — is the biggest FPY killer, so we tune it at the parameter level.
Per automated workstation. Line throughput is set by the bottleneck — usually cure time or RF acoustic calibration — so we break the ceiling by turning that station into a one-to-many parallel module.
Under 2,000 DPPM. The common consumer-mic returns — battery-swell compression, capsule moisture ingress, drop-induced cracks — all hinge on dispensing structural strength and seal consistency.
About half our earlier timeline. Moving a proven product to a new automated process skips EVT and concentrates on PVT — extreme stress testing to find where equipment parameters drift.
• SECT_02 // APPLICATIONS

Disposable Device & Wearable Bonding
Fast-fixture bonding and sealing for disposable medical devices and wearable housings — needle/cannula assembly, sensor and enclosure bonds. Light-cure cyanoacrylate chemistry (e.g. Loctite 4311), selected for biocompatibility-tested profiles and rapid line cure.

ANC Acoustic Chamber Sealing
Micro-gap filling and acoustic-chamber sealing for multi-mic ANC modules. A halogen-free, ultra-low-VOC outgassing formula eliminates diaphragm contamination and survives a 1.5 m drop onto concrete.

AI Server OAM Thermal Pad
Breaking the thermal-conduction bottleneck between high-compute AI chips and heat sinks. Excellent compression rebound and bleed-out resistance sustain peak heat dissipation through long-term 125°C thermal cycling.

Flexible RFID Antenna Encapsulation
Bend resistance and environmental protection for printed silver-paste antennas on flexible substrates. Excellent adhesion and weatherability keep RF signal transmission stable and distortion-free after 10,000 continuous 180° bend cycles.

As production shifts to Vietnam, Thailand, Poland, Mexico and Australia, we run a standardized global support network so your overseas plants keep the same SOPs and material supply as headquarters.
Adhesives face strict transport restrictions. We classify, package and document chemical materials to prevent border delays.
Realistic, reliable transit schedules. By centralizing distribution through Hong Kong, we route to match your production urgency and budget.
When production moves overseas, material consistency is critical. We make sure the exact chemistry validated by HQ R&D reaches the foreign plant with full documentation.
