Our philosophy at GBM is based on accuracy, consistency, and trust. We think that quality is made, not checked. At GBM, everything is done in accordance with strict rules and clear control procedures. Our main goal is to make sure that every mold and product you order meets your exact needs. The quality control team at GBM works hard to ensure you get the best products. We also invest in developing the quality control department.
At GBM, we continue to improve our production facilities. The company pays special attention to quality control and the research department. Our team studies new technologies and methods. We continuously strive to update our equipment for better results. We aim for 100% refinement in both quality and development.
The GBM quality assurance process covers every step from raw materials to final delivery. We follow proper quality control standards at every stage of our factory. We aim to keep accuracy and reliability. At GBM, we use advanced inspection tools, monitor data, and carefully record results. This way, every GBM mold and molded part meets precise engineering and performance needs.
All of our products are checked by GBM before use. We normally use supplier certificates to check the type of resin, metal inserts, and color batches. We check each batch for quality, moisture content, and strength. The workshop will only let approved items in. This step usually prevents quality issues and ensures that mold making and injection molding work smoothly.

We also measure each mold part and check it during machining. Our CNC, EDM, and polishing machines ensure tolerances up to ±0.01mm. We verify each fit and finish before assembly. GBM engineers specially review cooling, venting, and ejection designs.
Every mold undergoes a final inspection to confirm its readiness. We check for precision and stability before the first trial run.

After your mold is built, we run sample tests to check part accuracy and function. We measure each part using various measurement devices. Results are then compared to CAD data. If we need adjustments, we fine-tune the mold. Each trial record ensures the mold performs ideally before mass production starts.

Even during molding, we monitor key data—temperature, pressure, and cycle times — in real time. GBM operators follow standard operating procedures (SOPs). We do hourly in-process inspections to ensure the consistency of each part. Any deviation is corrected immediately.

At GBM, we also carefully inspect finished products for appearance, dimensions, and functionality. We use various measurement and visual inspection tools to detect any effects. All random samples go through detailed testing. We record every result in a report. This step ensures each product meets your exact needs before packaging or delivery approval.

Before shipping, we double-check all products and documents. Once checked, we pack, label, and confirm quantities for delivery. This final check verifies that your order meets 100% of your project needs. We typically store the inspection data and reports for traceability. Only after full approval, we pack the products and release them for delivery to you.

GBM typically uses various types of testing devices to check every part. Each tool is selected to check the specific parameters of the part. Some check the sizes, some analyze the shapes. Overall, we aim to ensure the highest quality of the part and meet your exact needs.
Coordinate Measuring Machine (CMM)
CMM checks part sizes in 3D. It checks accuracy, alignment, and tolerances. This equipment is ideal for verifying complex mold shapes.
Projector and Optical Comparator
This equipment typically visually checks the parts. With it, we measure contours, angles, and dimensions.
Height Gauge and Calipers
These tools measure vertical and linear dimensions. They are used to check small features and thicknesses.
Hardness Tester
This tool measures material strength and resistance. It ensures your molded parts and mold components meet the required durability standards.
Injection Molding Data Logger
The data logger records temperature, pressure, and cycle time during molding. It helps monitor the quality of the parts.
Visual Inspection System or Microscope
This equipment is the most typical one. We check the surface finish, minor defects, and fine details.
Check our certifications and standards. GBM strictly follows ISO and industry guidelines. Our goal is to ensure that every mold and product meets the highest quality standards.
