Industrial Anti-Vibration Mounts & Engine Isolators Manufacturer & Bulk Exporter to United States
Heavy-duty rubber-to-metal bonded cylindrical bobbins, bell mounts, and conical vibration isolators engineered to attenuate dynamic vibrations in automotive engines, tractors, and compressors.
45,000 sq.ft customs-bonded facility equipped with 50T–500T vacuum moulding presses, in-house mixing mills, and Class 5/7 cleanrooms.
Precision Polymer Engineering for Critical Industrial Operations
Industrial vibration mounts isolate dynamic mechanical disturbances, dampen structural resonance, and absorb shock loads generated by internal combustion engines, heavy rotary compressors, vibrating screens, and industrial power generation units. Using high-grade natural rubber (NR), chloroprene (Neoprene), and EPDM compounds, Horiaki tunes the dynamic-to-static stiffness ratio (cdyn/cstat = 1.25 to 1.45) to achieve isolation efficiencies exceeding 95% at nominal operational frequencies.
Our automated vulcanization bonding process applies proprietary multi-stage chemical primers and bonding agents to precision-machined, zinc-electroplated steel hardware. In destructive adhesion testing per ASTM D429 Method B (90° pull test), our rubber-to-metal interface consistently achieves 100% rubber failure with shear tear strength exceeding 12 MPa, ensuring zero debonding under severe automotive and off-highway operational abuse.
From standard cylindrical bobbins (male-male, male-female, female-female) to complex captive cab mounts, bell isolators, and heavy shear-compression pads, Horiaki offers end-to-end engineering from finite element analysis (FEA) to rapid CNC tooling and 100% lot testing on our computerized Universal Testing Machine (UTM).

Do you supply vibration mounts with imperial UNC/UNF threaded studs for the US market?
Yes. While standard metric threads (M6 to M24) are stocked, our CNC machine shop routinely produces studs in 1/4"-20, 5/16"-18, 3/8"-16, 1/2"-13, and 5/8"-11 UNC/UNF threads.
What is your testing protocol for rubber-to-metal bond integrity under US standards?
Every production batch undergoes destructive adhesion testing per ASTM D429 Method B. Failure must occur 100% within the rubber elastomer matrix at shear stresses exceeding 12 MPa, never at the metal adhesive interface.

Frequently Asked Questions
Common questions regarding compound formulations, tooling lead times, and export logistics.
How does Horiaki ensure that the rubber will not peel off the metal stud under load?
We perform automated grit-blasting to achieve a 50-micron surface anchor profile, apply dual-coat Chemlok bonding primers under monitored humidity, and vulcanize under high vacuum. Per ASTM D429 Method B, failure occurs inside the rubber matrix (>12 MPa), never at the bond interface.
Is Horiaki certified for automotive Tier-1 OEM supply?
Yes. Horiaki India operates under an ISO 9001:2015 quality management system and is an officially approved Tier-1 OEM production supplier to Daimler India Commercial Vehicles (BharatBenz).
Can you provide custom spring rates or non-standard thread configurations?
Yes. With our in-house CNC toolroom and computerized rheometer compounding lab, we can adjust polymer durometer and platen tooling to achieve exact customer-specified axial and radial spring stiffness rates.
