Horio Seisakusyo Co., Ltd
Most recent update: 2026-08-17
For global market, we provide the same high-quality products as in Japan in our Dalian development center. We use zinc alloy ingots imported directly from Japan.
PR message
1.Simultaneous development by specialized engineers:
development system for prototyping and mass production
2.The first flow solidification analysis simulation system for zinc die casting to minimized prototype loss
3.High-spec casting technology
-No deburring required
-Cast screws can be produced without cutting
-Long-lasting mold durability
These zinc die-cast hinges are currently used in mainstream slim notebook PCs.
By replacing stainless steel MIM (metal powder injection molding), they offer the following benefits:
① Equivalent strength ② Reduced costs ③ Shorter lead time
For all your zinc die-casting needs, trust Horio Corporation.
Our burr-free mold and casting technology ensures perfect JIS Class 2 cast screws.
They can be maintained even after nickel plating.
The precision is so great that you can't see the parting line unless you look closely.
We manufacture everything from molds in-house, even for small, complex-shaped products, so we can achieve high precision.
Plating adhesion is also good, and rust prevention effects add value.
With good LT, we can improve productivity.
The internal thread shape is also created from the mold and produced in a single molding process.
The product in the photo is die-cast using an 8-way slide core by clamping the mold, but the parting line is so precise that it is barely noticeable.
Please feel free to leave your internal thread products processing to us.
We can handle thin-walled products of various shapes, such as gear covers.
By taking advantage of the filling performance of zinc die casting, we have achieved a thickness of 0.25 mm in ultra-thin, high-rigidity chassis tests.
