Injection-molded plastic magnets for complex, lightweight parts

Injection molding of ferrite or NdFeB powder in a thermoplastic binder (PA or PPS) to make bonded-magnet parts with 3D geometry, insert-molded shafts/gears, and no post-grind in the cases the company describes.

Problem solved

Sintered magnets are limited to simple block/arc shapes, chip easily, often need grinding, and lock the design to a high rare-earth sintered grade. Plastic-magnet injection is used when the buyer needs complex 3D geometry, thin walls, insert-molded metal, lower inertia, or a ferrite-bonded option that does not depend on sintered NdFeB.

Two-shot in-mold integration of magnet and structural resin

Sequential or insert two-shot molding that joins a plastic-magnet shot to a structural resin or insert (shaft, gear, cover) inside the tool, removing a later adhesive assembly step.

Problem solved

Bonding a magnet to a cover, shaft or gear adds assembly labor, adhesive-strength inspection and positional scatter. Two-shot / insert molding is used when the buyer wants the magnet and neighboring structure as one molded unit with tool-controlled alignment.

Custom Pouch-Cell Tab Lead Manufacturing

Custom development and contract production of tab leads (cell terminals) for laminate-type lithium-ion pouch cells, with in-house sealant film lamination technology ensuring electrolyte leakage prevention and long-term seal integrity.

Problem solved

Pouch cell tab leads must provide a hermetically sealed electrical feedthrough between the cell interior (organic electrolyte) and external circuit, while withstanding the cell assembly heat-seal process and long-term exposure to electrolyte. Improper tab lead design causes electrolyte leakage, cell degradation, and fire risk. Standard off-the-shelf tab leads do not accommodate the wide variety of cell capacities, form factors, and current ratings required by custom pouch cell projects.

End-to-end CFRP/GFRP composite development from custom resin formulation to integrated assembly

60-year track record of full-spectrum CFRP product creation: in-house thermoset resin formulation, structural design and FEM analysis, mold fabrication, autoclave and filament-winding molding, 5-axis machining, coating, and system-level integration. Supports volume from single prototypes to 10,000+ units/month.

Problem solved

Overseas buyers of precision CFRP components — especially for semiconductor equipment, wind energy, and medical devices — typically must coordinate separately with a resin formulator, a design house, a molder, and a machinist. This fragmented supply chain multiplies qualification cost, lead time, and IP exposure risk.

Custom thermoset resin formulation for specialty composite applications

In-house development of custom epoxy, phenolic, and other thermoset resin systems tailored to specific application requirements — flame retardancy, heat resistance, chemical resistance, fast cure, or special surface appearance — integrated with CFRP/GFRP molding at production scale.

Problem solved

Standard prepreg systems from major suppliers (Toray, Hexcel) are optimized for aerospace structural properties but do not address application-specific constraints like flame/smoke/toxicity for public transit, chemical resistance for semiconductor wet processes, or fast-cure cycles for high-volume consumer-electronics production. Customers requiring specialty resin properties must either develop them in-house or work with multiple suppliers.

Ultra-thin composite copper foil for lithium-ion battery anode current collectors

PET film (6µm) base with copper plating (~1µm per side) achieving 4µm total thickness, half the weight, and one-quarter the copper consumption of conventional rolled copper foil, enabling lighter, more resource-efficient battery cells.

Problem solved

Conventional rolled copper foil for Li-ion battery anodes is limited to ~8µm minimum thickness before handling becomes impractical (tearing, wrinkling). Thinner foil could reduce battery weight and material cost, but thin copper alone is too fragile. Teikoku Ion's composite approach uses a polymer film substrate for mechanical strength while plating ultra-thin copper layers for conductivity, breaking the thickness barrier.

PowerBinder natural-polymer water-based electrode binder for sustainable battery manufacturing

Alginate/gelatin/chitosan-based water-processable binders replacing NMP-solvent PVDF systems for lithium-ion battery cathodes, enabling safer, lower-cost, environmentally friendly electrode manufacturing.

Problem solved

Conventional Li-ion battery cathode manufacturing uses PVDF binder dissolved in NMP (N-methyl-2-pyrrolidone), a toxic, flammable organic solvent requiring expensive solvent recovery systems and posing worker safety and environmental risks. PowerBinder enables water-based cathode slurry processing, eliminating NMP entirely.

MAGesty — Rare-Earth-Free Iron Nitride (Fe16N2) Nanocomposite Magnet Material

A rare-earth-free permanent magnet material based on iron nitride (Fe16N2) and Sm2Fe17N3 nanocomposite powder, processable by injection molding or compression molding into bonded magnets for automotive, drone, and industrial motor applications.

Problem solved

Global dependence on China-sourced rare earths (Nd, Dy, Tb) for permanent magnets creates supply-chain risk, price volatility, and geopolitical vulnerability for EV, wind turbine, and industrial motor manufacturers. MAGesty reduces or eliminates rare-earth content while remaining compatible with existing bonded-magnet production lines.
