Silicone Moulded Products Manufacturer & Bulk Exporter to Spain
Cleanroom molded liquid silicone rubber (LSR) and high-consistency silicone components certified to FDA 21 CFR 177.2600 and USP Class VI.
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
Silicone elastomers (polydimethylsiloxane) deliver unmatched thermal endurance, retaining flexible elasticity across an extraordinary operational temperature spectrum from -60°C to +250°C (-76°F to +482°F). Unlike organic rubbers, the inorganic silicon-oxygen (Si-O) polymer backbone is completely impervious to ozone, ultraviolet (UV) radiation, corona discharge, and extreme atmospheric weathering.
For medical devices, infant care, and food processing applications, Horiaki processes ultra-pure platinum-cured liquid silicone rubber (LSR) in closed-loop injection moulding machines. Post-cured in temperature-controlled cleanroom ovens, our components contain zero phthalate plasticizers, zero heavy metals, and pass USP Class VI systemic toxicity, intracutaneous reactivity, and cytotoxicity tests per ISO 10993.
In the electric vehicle (EV) and electronics sector, Horiaki engineers flame-retardant silicone thermal gap pads (thermal conductivity 1.5 to 8.0 W/m·K) meeting UL 94 V-0 flammability ratings. These high-compliance pads bridge microscopic surface irregularities between lithium-ion battery cells and cooling plates, ensuring rapid heat dissipation, electrical insulation (dielectric strength > 20 kV/mm), and shock absorption.

Frequently Asked Questions
Common questions regarding compound formulations, tooling lead times, and export logistics.
What is the difference between Platinum-Cured and Peroxide-Cured silicone?
Peroxide curing is economical for generic industrial seals but can leave acid residues and volatile byproducts. Platinum curing produces ultra-pure, non-yellowing, odor-free silicone with superior clarity and zero peroxide byproducts, mandatory for FDA and USP Class VI compliance.
Can Horiaki customize the thermal conductivity and thickness of EV thermal pads?
Yes. We formulate and calendared-cure thermal gap pads with conductivities ranging from 1.5 W/m·K to 8.0 W/m·K, in custom thicknesses from 0.5 mm to 10.0 mm, supplied as die-cut pads or continuous rolls with one-sided fiberglass reinforcement.
How does Horiaki ensure that food-grade silicone seals do not affect taste or odor?
Our food-grade compounds are mixed with virgin vinyl silicone polymers and treated fumed silica. All parts undergo a mandatory 4-hour post-cure bake at +200°C to eliminate all volatile oligomers, ensuring complete organoleptic neutrality.
What cleanroom manufacturing standards does Horiaki operate for medical silicone?
Our medical and infant-grade silicone moulding is housed in an ISO Class 7 cleanroom equipped with HEPA filtration, positive air pressure, and automated closed-loop LSR dosing systems.
What are the export delivery options for silicone components from Chennai?
Pre-production evaluation samples and urgent prototype pads ship via DHL/FedEx Express Air within 48–72 hours. Production lots ship on ISPM-15 wooden pallets in sea containers via Chennai Port (INMAA) to international ports worldwide.
