01
Functional Range
Motion Functions: Slide, stop, rotate, protect—engineered components that perform reliably.
Bearings (Slide) that control the coefficient of friction (CoF) and minimize wear.Friction materials (Stop) that deliver reliable braking and holding performance.Polymer gears (Rotate) that transmit power efficiently.Seals (Protect) that prevent leakage and reduce damage to the counterface.
Across these functional components, we help improve the reliability of machines and equipment.
02
Application Range
Industry Coverage: From infrastructure and steel plants to collaborative robots.
From heavy-duty equipment in steel-making and shipbuilding—designed to run continuously under high loads—to polymer gear reducers that transmit rotational power with precision. Our long-standing adoption across applications that demand both strength and precision is proof of STARLITE’s reliable
03
Temperature Range
Temperature Range: Usable from -200°C cryogenic to 800°C high heat environmental temperature.
STARLITE maintain stable performance even in extreme environments—high-temperature ranges where polymers can soften or lose performance, and cryogenic conditions down to liquid-hydrogen temperatures. For operating conditions that are challenging for conventional materials, we combine material engineering with upfront simulation and testing to define the optimal specifications.
04
Lubrication Range
Environments: Optimized for water, oil, grease, or no lubrication.
Even in dry-running environments where lubricants can’t be used—and under harsh conditions where seawater, chemicals, or slurry may enter—we maintain smooth motion and high wear resistance. Across a wide range of operating environments, we support reliable, long-lasting performance you can count on.
05
Material Range
Materials: Thermosets, fluoropolymers, engineering plastics, biomass and recycled grades.
BAKES, based on heat-resistant polymer composites. ALP, based on fluoropolymers. S-BEAR, based on high-performance engineering plastics. Starting from material design and selection, we translate requirements into the optimal geometry—delivering an end-to-end solution from material to final shape.
06
Process Range
Processes: Injection, compression, foaming, FRP, continuous long-length forming.
STARLITE support a wide range of processes—from injection molding of difficult high-performance polymers to thermoset molding and FRP/composite processing. Leveraging proprietary technology for seamless long-length components, we recommend the optimal process based on material behavior and your performance requirements.
07
Geometry Range
Scale: Millimeter parts to meter-class components and units.
From small precision parts requiring fine tolerances to seamless long-length products and meter-class large components, we deliver the specifications you need with minimal constraints on size or geometry. We can also design not only individual parts but complete assemblies—units that incorporate surrounding mechanisms as an integrated system.
08
Validation Range
Evidence: CAE prediction plus in-house testing for data-backed confidence.
We use simulation to establish an upfront outlook, then confirm performance through real-world testing at our in-house evaluation center. By iterating between prediction and verification, we build data-backed confidence and deliver reliably validated quality.
Starlite Core Tech
Development & Design. Implementation. Validation & Testing. Connecting the full workflow end-to-end to bring the optimal solution to life is Starlite’s core technology.
Analysis & Validation
Before production, we make performance visible and verify it upfront. We simulate not only moldability, but also how the part will behave under real operating conditions. This helps reduce prototype iterations and rework, keeping development moving smoothly.
Performance Testing
We conduct testing at our in-house evaluation facilities under conditions that reflect real-world use. We quantify wear and friction (sliding resistance) and use the results to objectively verify the assumptions and predictions from simulation.
Molding & Tooling Engineering
Even for materials that are difficult to mold, we have established mold design and manufacturing processes to achieve the intended geometry and precision. We reflect simulation results in tooling design and select the optimal molding method, enabling high-accuracy, repeatable molding.
Production System
STARLITE support everything from one-off prototypes to mass production at volumes of tens of thousands of parts per month. By coordinating our manufacturing sites in Japan and overseas, we maintain required quality while ensuring stable, on-time supply.
Materials Design
We design material combinations and formulations to match operating conditions such as temperature, load, and counterface material. By engineering the material to meet the target performance, we translate required properties into real, usable function.
Geometry & Unit Design
We design part geometry to fully leverage material performance—and can extend to unit-level design that includes surrounding mechanisms. Using upfront simulation, we confirm motion behavior and thermal effects, then refine geometry to match the operating environment—improving factors such as low-friction movement and heat dissipation.

Materials Development
Advancing Chemical Recycling
Phenolic resins have long been considered difficult to recycle. In a joint research project with the University of Fukui, STARLITE are exploring a technology that introduces a special acetal linkage into the resin structure—aiming to enable chemical depolymerization and open a path toward circular use.
Controlling Friction with Plant-Based Materials
STARLITE is developing friction materials that use biomass-derived raw materials, with the goal of moving away from petroleum-based inputs. By overcoming challenges in cost and material performance, we aim to commercialize these as next-generation materials with a lower environmental footprint.
Responsible Manufacturing
Turning Production Scrap into Resources
In the production of our mass-produced fluoropolymer products, offcuts and scrap are generated during processing. Instead of discarding them, we grind and reuse the material. By developing our proprietary ram extrusion process, we aim to build a system where production scrap is recovered and reborn as usable product material.
Reducing Plastics in Packaging
We are gradually replacing disposable plastic cushioning and packaging materials used for shipping with reused cardboard, including material recovered from waste corrugated boxes. This step helps reduce single-use plastics and supports more sustainable logistics.
