Complex Precision Injection Molds Built for Stable Production
GBM helps OEMs, product companies and injection molders turn complex plastic part designs into reliable molds and production-ready molded components.
From DFM analysis and mold engineering to mold manufacturing, trial, injection molding and assembly, every project is managed by one experienced team.
Your drawings and project information will be treated as confidential.

When a Mold Project Is Complex, Small Mistakes Become Expensive
Too Many Mold Revisions
Weak early analysis leads to repeated tooling changes and delayed production.
Unstable Part Dimensions
Tight tolerances become difficult to maintain from trial samples to mass production.
Complex Ejection Failures
Slides, lifters, threads and inserts create higher risks of damage and production downtime.
Poor Material Bonding
Two-shot and overmolded parts may suffer from weak bonding, flash or inconsistent appearance.
Unclear Project Progress
Buyers cannot afford to wait weeks without knowing the real tooling status.
A Mold That Cannot Run Locally
Export molds must match the customer’s machine, standards, connectors and maintenance practices.
GBM addresses these risks before steel cutting—not after the mold has already become a problem.
Core Injection Tooling Solutions
Built around the part structure, production target and long-term operating requirements—not a standard mold template.
Two-Shot Mold
Integrate two colors or materials into one molded component for better sealing, grip, appearance and functional performance.
Overmolding Tool
Overmold soft-touch, sealing or shock-resistant materials onto rigid plastic or metal substrates.
Insert Molding Tool
Precisely position metal terminals, pins, nuts and other inserts during molding to reduce assembly and improve structural reliability.
Automatic Unscrewing Mold
Automated internal and external thread release for threaded fittings, valves and high-performance polymer components.
Precision Connector Mold
Precision tooling for high-density terminals, fine-pitch connectors, fuse blocks and insert-molded electrical components.
Complex Precision Injection Mold
Engineered for products requiring multiple sliders, lifters, interchangeable inserts, deep cavities or demanding dimensional control.
One Team from DFM to Stable Mass Production
RFQ and Drawing Review
Review customer drawings, material, annual volume, mold standards and production requirements.
DFM and Feasibility Analysis
Identify draft, wall thickness, undercut, gate, ejection, sealing and dimensional risks before tooling begins.
Mold Design and Moldflow
Develop the mold structure, runner, cooling and ejection solution based on the product and production target.
Precision Mold Manufacturing
CNC, EDM, component inspection, mold fitting and assembly are managed through an in-house tooling process.
Mold Trial and Validation
Provide trial samples, molding parameters, inspection reports, trial pictures and video updates.
Injection Molding and Assembly
Support low-volume production, mass production, secondary operations, assembly and export delivery.
The same project team follows the mold from the first drawing review through final production approval.
Discuss Your Project RequirementsEngineering Decisions Made Before Steel Cutting
Our engineering team conducts comprehensive analysis on part structure and molding feasibility to ensure stability:
- Draft angle and part release
- Wall thickness and sink risk
- Undercuts, sliders and lifters
- Gate type and gate location
- Weld lines and air traps
- Cooling layout and cycle time
- Dimensional tolerance and warpage
- Insert positioning
- Two-shot material compatibility
- Internal and external thread release
- Mold machine compatibility
- Export tooling standards
Complex Projects We Are Built to Handle
View More Mold ProjectsHigh-Insert-Count Fuse Block Mold
More than 1,400 precision inserts and fragile profiles created a high risk of component damage and maintenance downtime.
GBM redesigned the insert and mold structure to improve component strength, maintainability and molding stability.
The new mold received approval after the first trial and resolved the previous maintenance problem.
Large Two-Shot Mold
A large multi-material automotive component required controlled material transfer, complex lifters and a stable hot runner system.
A 5.5-ton two-shot mold was developed with hydraulic lifters and a production-focused mold structure.
The mold supported stable two-material molding and the customer’s production requirements.
High-Temperature Threaded PEEK Part
The component included internal and external threads and required molding at high mold temperature.
GBM developed an automated unscrewing structure with dedicated heating and temperature-control considerations.
The mold achieved reliable thread release and stable production.
Fast-Delivery Stack Mold
The customer needed higher output without significantly increasing production floor space or machine capacity.
GBM developed and completed the stack mold project from design to shipment in approximately nine weeks.
The stack mold increased production efficiency and reduced unit manufacturing cost.
Tooling That Is Proven Through Real Production
A mold is not complete when the steel is finished. It is complete when it can run consistently in production.
