How to Work With Us
We know that outsourcing manufacturing can feel risky. We have designed our workflow to be transparent, communicative, and disciplined. Here is what happens when you partner with GBM:
01
Inquiry & Feasibility Study
It starts with a conversation. Send us your 3D data or drawings. We don’t just throw a generic price at you; our engineers actually dive into the design. We check the part geometry, analyze the material selection (especially for complex dual-material bonding), and review your tolerance needs. We look for potential pitfalls before they cost you money. Within 24 hours, you’ll get a precise quote and honest technical feedback—so you know exactly what you're getting into.
02
Engineering & DFM Review
We hate surprises as much as you do. That’s why before we touch a single piece of steel, we simulate everything. We perform a comprehensive Design for Manufacturability (DFM) analysis and run Moldflow simulations. This lets us see into the future—predicting risks like sink marks, air traps, or warpage. We’ll sit down with you (virtually) to optimize the design, ensuring it’s not just "moldable," but optimized for efficient mass production.
03
Tooling Design & Approval
This is where the blueprint comes to life. We create detailed 2D and 3D mold designs, planning every cooling channel and ejection pin placement. We don't keep secrets—we share the full layout with you for review. We discuss the cooling efficiency, the gate locations, and the moving mechanisms. Construction only begins when you say "Yes." We ensure you are 100% confident in the design before we start machining.
04
Manufacturing & Weekly Updates
We know waiting is the hardest part, so we make sure you’re never left wondering, "What's happening with my mold?" During the machining phase, you become part of our workshop. Every week, your dedicated project manager will send you a Weekly Progress Report. This isn't just a spreadsheet; it includes real photos and videos of your mold on our CNC and EDM machines. You can track the steel cutting, electrode machining, and fitting process as if you were standing right here on our factory floor.
05
T1 Trial & Validation
This is the exciting part. We load your mold into our in-house injection machines for the first trial shot (T1). But we don't just look at the parts; we scrutinize them. We use our CMM equipment to generate full Dimensional Reports, checking against your original tolerances. We then ship the actual T1 samples (and the data) directly to your desk. You get to hold the product, test the fit, and verify the function yourself.
06
Texture & Final Finish
Once you confirm the samples are dimensionally correct, we focus on the aesthetics. Whether you need a specific VDI texture for grip or a mirror polish for optical clarity, this is when we apply the final surface treatments. But we don't stop there. We conduct a final "dry-cycle" test—running the mold empty for hours—to ensure every slider, lifter, and pin moves silky smooth. We make sure the tool is robust and ready for the rigors of high-volume production.
07
Global Logistics & Delivery
Global Logistics & Delivery We treat your mold like a precision instrument. Before shipping, we thoroughly clean it, apply professional rust prevention, and vacuum-seal it to protect against humidity. Whether you need it shipped fast via air or economically via sea, we handle the logistics paperwork and customs clearance assistance. We don’t consider the job done until the mold arrives safely at your facility and is producing parts on your machine.

How We Save Your Injection Molding Cost?
Price matters, but value matters more. We help you reduce the Total Cost of Ownership in four specific ways:
Smart Engineering (DFM)
By identifying design flaws before mold making, we prevent expensive tooling modifications and “re-dos” later. A smart design changes implies a cheaper, faster mold.
Cycle Time Reduction
Our mold flow analysis allows us to design optimal cooling channels. A mold that cools 5 seconds faster can save you thousands of dollars in part costs over a large production run.
Integrated Assembly
By using 2-Shot or Insert Molding, we combine multiple assembly steps into one molding cycle. This reduces your labor costs and inventory complexity.
Mold Longevity
We use high-quality German and American imported steel. A GBM mold lasts longer, meaning you won’t have to pay for repairs or replacement tools halfway through your product’s life.

What is Injection Molding and How Does it Work?
Injection molding transforms raw resin into finished components by injecting molten material under high pressure into custom-built metal molds.
At GBM, we treat this process as a rigorous science. Equipped with over 40 high-precision machines from Fanuc and Makino, we achieve micron-level accuracy with tolerances as tight as ±0.01 mm.
This ensures every detail of your complex automotive or electronic components is captured with zero deviation, scaling effortlessly from prototypes to millions of units.
What is the best material for injection molding?
The “best” material depends entirely on your application’s demands.
While many standard shops only handle common resins like ABS, GBM specializes in mastering “difficult” and high-performance engineering plastics.
We expertly mold high-temperature materials such as PEEK, PPS, LCP, PSU, and Glass-Filled Nylon. With precise mold temperature control to prevent warping, we provide solutions for sectors where failure is not an option.
What are the 4 types of moulding?
Standard molding is just the beginning; complex projects require advanced, multi-material techniques.
GBM specializes in four high-value mold types: 2-Shot (dual-injection), Insert Mold, Unscrewing Mold, and Stack Mold.
Our 2-Shot and Insert molding expertise allows us to achieve a 100% molecular bond between rigid and soft materials (like PC+TPU), combining multiple assembly steps into one cycle to significantly reduce your labor costs.
What are the advantages and disadvantages of injection moulding?
The primary advantages are seamless scalability, unparalleled repeatability, and extremely low per-part costs for high-volume production.
The main disadvantage is the high initial tooling cost.
GBM mitigates this risk by using high-quality German and American imported steel to ensure mold longevity, meaning you won’t pay for replacement tools halfway through your product’s life. Furthermore, our mandatory Design for Manufacturability (DFM) review prevents expensive modifications and “re-dos” down the line.
How to improve the injection moulding process?
Process improvement must happen before a single piece of steel is cut.
We utilize Scientific Mold Validation and rigorous Moldflow simulations to predict and prevent issues like air traps, weld lines, or warpage.
By engineering optimal cooling channels, we achieve significant cycle time reduction—a mold that cools just 5 seconds faster can save you thousands of dollars over a large production run.
