STEP · IGS · STL 2D Drawings Physical Samples
01

By Drawing (来图)

Send 2D/3D CAD. DFM review, cavity layout, cost optimization returned in 48h.

02

By Sample (来样)

Mail us a reference part. We 3D scan, re-engineer and improve durability/fit.

03

By Concept

Describe the function. Our design team delivers renders & prototypes in 7 days.

04

Co-Development

Joint IP projects -- we invest tooling for long-term volume commitments.

04 · Functional Design

Anti-Slip · Shock-Absorb · Secure Fixation

Training accessories live in wet, high-friction, high-impact environments. Our geometries and material durometers are tuned for every contact point.

Anti-Slip Textures

Micro-ribbed, waffle and diamond-knurl silicone surfaces maintain grip even on wet hands -- tested to coefficient of friction > 0.65.

Shock Cushioning

Dual-durometer silicone (30A core / 50A skin) absorbs impact on paddles, kickboard edges and resistance band grips without rebound fatigue.

Secure Fixation

Interlock ridges, lip seals and compression-fit sockets lock parts in place -- zero loosening after 10,000+ pool cycles.

05 · Tolerance & Fit

Dimensional Tolerance & Assembly Matching

Every silicone part must mate flawlessly with the plastic housing it bonds to. CMM-verified molds, calibrated presses and in-line SPC keep every batch within spec.

06 · Multi-Material Engineering

Combination Materials & Over-Molding

Soft silicone bonded onto rigid plastic, metal inserts encapsulated, hybrid colors co-injected -- one process, one part, zero adhesives.

S+P

Silicone + Plastic

LSR over-molded onto ABS, PP or Nylon substrates with chemical bonding -- no delamination.

S+M

Silicone + Metal

Stainless inserts encapsulated for durable grip cores, buckle pins and attachment points.

2K

Two-Shot (2K)

Dual-color or dual-hardness in one injection cycle -- brand accents and ergonomic grips.

TPE

TPE / TPU Blends

Alternative soft-touch materials when recyclability or cost-point requires non-silicone.
