Guangdong Yingtai High Precision Technology Co., Ltd. delivers trusted liquid silicone rubber (LSR) and overmolded solutions optimized for energy and power vehicle industries. Backed by two decades in advanced silicone molding and injection technology, our Dongguan-based factory serves the evolving needs of electric vehicles (EVs), hydrogen-powered units, and hybrid drivetrains with durable, heat- and chemical-resistant silicone components.
The energy and power vehicle sector is undergoing a transformative phase driven by stricter emission regulations, rapid electrification, and a global pivot toward sustainable transport. Silicone parts, particularly those manufactured with liquid silicone rubber (LSR) injection molding, play crucial roles in sealing, insulation, vibration dampening, and component protection under extreme conditions. Our expertise at Guangdong Yingtai High Precision Technology Co., Ltd. — supported by a 35,000 sqm advanced industrial park in Dongguan — focuses on integrating high-performance silicone materials into powertrains, battery packs, and electronic assemblies for electric and hybrid vehicles.
The global LSR market for automotive and industrial applications is expected to grow consistently over the next decade. For instance, the Grand View Research 2030 report projects the LSR market to rise from USD 2.81B in 2023 to nearly USD 5B by 2030. This uptick is fueled by demand for silicone parts that withstand thermal cycling, exposure to oils, fuels, UV radiation, and harsh operational environments typical of energy vehicles.
Navigating international supply chains while meeting ISO 9001, ISO/TS 16949 automotive standards, and RoHS and REACH compliance requires a manufacturing partner that blends technical mastery with agile production capabilities. Our factory’s investment in advanced liquid injection molding machines, including 55 sets dedicated to LSR and 80 plus for plastic injection, positions us to deliver consistent quality at scale — whether your order is for customized prototypes or high-volume production batches.
Recognizing procurement realities, we work closely with engineers and operations managers to align silicone part design, material selection, and mold tool precision with project timelines and cost parameters. We understand how critical it is to avoid tooling over-runs or material wastage — frequent procurement pitfalls in silicone manufacturing.
Our manufacturing incorporates precision LSR injection molding, supported by a well-equipped suite of machines — including 20 hydraulic presses for solid silicone and over 30 advanced CNC molds manufacturing devices. This integration allows us to control every phase, from mold development to final inspection, reducing potential defects or wastage.
Key material characteristics we focus on include:
| Property | Typical Value | Test Standard |
|---|---|---|
| Hardness (Shore A) | 25 – 70 | ISO 7619-1 |
| Tensile Strength (MPa) | 7 – 14 | ASTM D412 |
| Elongation at Break (%) | 500 – 850 | ASTM D412 |
| Thermal Conductivity (W/mK) | 0.2 – 0.26 | ISO 22007-2 |

Our engineering department leverages CAE injection molding simulations tuned with industry-grade LSR rheological data (cf. MDPI polymer study) to optimize mold designs, minimizing defects like flash and sink marks. This care enhances production yield and shortens development lead times — a frequent bottleneck for OEMs.
OEM and ODM Manufacturing: With the modular tooling and intellectual manufacturing systems in place, we support customized design adaptation, small-batch prototyping, and scale-up production. Learn more about how you can explore OEM options with Yingtai.
From battery insulation to powertrain sealing, our silicone components integrate into:
Selecting the right silicone formulation in sync with application needs is crucial. For example, certain gaskets require low compression set to prevent leaks, while cable seals benefit from higher Shore A hardness for abrasion resistance. Our technical team advises buyers on such nuances, ensuring performance aligns with vehicle certification criteria and longevity expectations.
Managing procurement of silicone parts for energy vehicles involves balancing quality, delivery, and cost. Here are practical considerations we advise:
“Many buyers underestimate the importance of precise rheological data and mold flow simulations — skipping this often leads to substandard parts or costly remolding.” — Senior Production Engineer, Yingtai
At Guangdong Yingtai, we embed CAE simulation insights, strict incoming material inspections, and ISO-certified production workflows into every project. This practice significantly reduces risk exposure and supports consistent supply—whether you require one-off prototypes or continuous shipments.
