Engineering Challenges We Help Solve

Tight Dimensional Tolerance

Precision machining and controlled molding processes ensure consistent critical dimensions and reliable product performance.

Multi-Cavity Balance

Optimized runner and gating systems deliver uniform filling, pressure, and part quality across every cavity.

Flash & Parting Line Control

High-precision mold alignment and carefully fitted parting surfaces minimize flash and visible parting lines.

Sealing & Functional Interfaces

Critical sealing and connection areas are precisely manufactured to prevent leakage and ensure secure assembly.

Clean Mold Construction

Corrosion-resistant steel, clean mold design, and contamination-controlled manufacturing support demanding medical applications.

High-Volume Production Stability

Robust mold construction, balanced cooling, and wear-resistant components maintain stable production over long molding cycles.

Case Study

We bridge the gap between innovative design and practical manufacturing.

Pipette Tip Injection Mold

Part Name: Pipette Tips Part Dimension: Approx. Ø8 × 70 mm Part Material: Medical-grade Polypropylene (PP) Cavities: 96 Cavities Mold Steel: ASSAB Stavax ESR HRC48~52 Mold Size: 850 × 700 × 600 mm Mold Weight: 2,200 kg Exported to USA

Pipette Tip Mold Trial

Challenges The long, thin-walled tapered structure is prone to short shots, deformation, and uneven shrinkage during molding. With 96 cavities, maintaining consistent filling, dimensions, and part weight across all cavities is highly challenging. Solutions A balanced hot runner and optimized gating system ensure uniform filling and stable pressure in every cavity. High-precision S136 inserts and well-balanced cooling channels minimize dimensional variation and deformation. Precision machining, controlled clean production, and strict cavity-by-cavity inspection ensure reliable sealing and consistent product quality.
