FAQ
Q: Can this heavy duty hinge handle vertical adjustments for thick insulated freezer doors?
A: Yes. The right-hand hub structure features integrated machined slots and adjustable hex nuts. This allows installers to easily micro-tune the vertical height and the forward/backward compression sealing depth, ensuring a perfect airtight lock against soft rubber gaskets.
Q: Do you supply the hinge fully assembled with the pins, nuts, and washers included?
A: Absolutely. We operate as a full-service OEM contract manufacturing partner. We perform the casting, post-CNC drilling, surface brushing, and final hardware integration in-house. You will receive a fully assembled, ready-to-bolt-down heavy hinge kit.
Q: Why choose an investment cast heavy hinge over cheap stamped or welded plates?
A: Stamped or welded alternatives distort easily and can experience critical seam failure when supporting 100kg+ commercial freezer or marine doors. Our silica sol lost wax technique outputs a fully dense, uniform, single-piece metallic grain structure with massive tensile and yield margins, ensuring elite long-term safety.
