Our Core Services

Design for Manufacturing (DFM) Analysis

This is where all our projects begin and where we create the most value for our clients. Before tooling begins, our engineers provide a comprehensive 10+ page DFM report that identifies and resolves potential design issues through software simulation and experience-based analysis.

  • Material flow analysis
  • Weld line prediction
  • Air trap risk assessment
  • Warpage analysis
  • Cooling system optimization

Precision Mold Design & Manufacturing

Our in-house tooling workshop is the core of our quality and speed guarantee.

  • Mold types from single cavity prototype to 128-cavity hot runner production molds
  • Premium mold steels: P20, 718H, S136, H13 from LKM, ASSAB, Gröditz
  • Advanced techniques: sliding cores, lifters, multi-stage ejection, gas-assisted molding

Insert Molding

We integrate metal inserts, screws, shafts, electronic contacts, or flexible circuits into plastic parts during the molding process.

  • Enhanced product strength and durability
  • Simplified assembly process
  • Electrical connectivity integration
  • Automated or manual insert placement

Overmolding

This process involves molding a soft material (TPE, TPU, LSR) over a rigid plastic substrate (ABS, PC).

  • Improved grip and anti-slip properties
  • Waterproof sealing capability
  • Enhanced aesthetics
  • Vertical injection machines available

Cleanroom Molding

Our ISO Class 8 (100K) cleanroom environment meets the strictest requirements for particle contamination control.

  • Temperature and humidity control
  • HEPA air filtration
  • All-electric injection machines
  • Strict contamination prevention protocols

Design Engineering Guidelines

Uniform Wall Thickness

Principle

Maintain consistent wall thickness throughout the part.

Reason

Prevents cooling-related issues like sink marks, warpage, and internal stress.

Recommendation

Use gradual transitions when wall thickness must change.

Draft Angles

Principle

All surfaces parallel to the mold opening direction need draft angles.

Reason

Ensures easy part ejection and prevents surface damage.

Recommendation

1°-2° for smooth surfaces, 3°-5° or more for textured surfaces.

Radii & Fillets

Principle

Avoid sharp corners, use radius transitions.

Reason

Prevents stress concentration and improves material flow.

Recommendation

Internal radius should be at least 0.5 times wall thickness.

Our Quality Control Process

Quality is built into our process, not just inspected at the end.

IQC (Incoming Quality Control)

All raw materials are verified for specifications, color, and performance certificates before warehouse entry.

IPQC (In-Process Quality Control)

Regular inspections during production using calipers and gauges. First Article Inspection (FAI) is mandatory for each batch.

FQC (Final Quality Control)

Final inspection using CMM and vision systems according to AQL standards or customer requirements.

Documentation Provided

  • Full dimensional inspection reports (FAIR)
  • Material certificates (CoC)
  • RoHS/REACH compliance declarations

What is Injection Molding?

Injection molding is an efficient, repeatable manufacturing process where molten plastic resin is injected under high pressure into a metal mold cavity. After cooling and solidification, it forms the desired plastic product. This process has become a cornerstone of modern manufacturing due to its ability to mass-produce complex precision parts at extremely low unit costs.

vs. 3D Printing

While injection molding has higher initial tooling costs, it offers extremely low per-unit costs and is ideal for large-scale production (>1,000 pieces). 3D printing has no tooling costs but is better suited for prototypes and very small batches due to higher unit costs and slower speed.

vs. CNC Machining

CNC machining offers broader material options (including metals) and extreme precision, suitable for low to medium volumes. Injection molding provides superior cost-effectiveness and speed for medium to high-volume plastic parts production.

vs. Die Casting

Die casting is specifically for metal parts (like aluminum and zinc alloys) with similar process principles, while injection molding is specialized for plastics.
