GBM Unscrewing Mold and Molding Services
Unscrewing mold is a special type of injection mold designed for threaded parts only. These threads can be inside or outside the part. With an unscrewing mold, you can create fully formed threads while molding.
Unlike traditional molds, unscrewing molds work differently. First, they fill the mold (including the thread shape) with molten plastic. After the plastic has solidified, the threaded core rotates and unscrews the part. The whole process follows strict quality controls. As a result, the parts come out smooth and scratch-free.
At GBM, we produce threaded parts for a variety of industries. Our primary focus is on the auto and medical industries. However, we also make molds for military, industrial, and consumer industries. As a custom manufacturing company, we specialize in research and development. Our team designs each mold to match the exact thread size you need. As a result, the mold produces consistent parts even after millions of cycles.
Moreover, our unscrewing injection mold design uses a safe and reliable mechanism. We do not rely on cheap technology, which may compromise durability and performance. The molds we produce can handle deep threads with tight tolerances up to ±0.01mm.
You might be looking for caps, connectors, or small parts. GBM produces threaded features with the precise dimensional control required for dependable assembly. With over 13 years of industry experience, we have expanded our capabilities. Now we have modern tooling, quality control, and logistics. In addition, we always strive to maintain the highest standard. If you are looking for reliable molds and molding parts, the company is always ready to help.

Unscrewing Molding Key Features
Unscrewing mold is different from regular molding. It has special features for making threaded parts that you won’t find in other mold types. These features are technically necessary for cleaner threads and accurate shapes.

Deep or Precise External/Internal Threads
An unscrewing mold can produce deep, precise threads. It turns and removes the part safely. The controlled process keeps every thread clean and strong. The unscrewing process ensures consistent thread-to-thread engagement for reliable assembly.
Minimal Surface Marring
The controlled (programmed) unscrewing prevents surface marring. It avoids the surface damage typically associated with stripper plate demolding. Rather than forcibly stripping the part from the mold, the unscrewing mechanism rotates to release it, resulting in a smooth, defect-free surface finish.
Tight Sealing or Functionality Requirements
One of the critical steps in making threads is ensuring that the sealing meets dimensional requirements when the threads are closed. Unscrewing molds must create threads that seal tightly. It is crucial for bottle caps, medical cases, or connectors.
Repeated High-Cycle Production
Unscrewing molding systems are strong and reliable. They can run thousands of cycles without losing accuracy. It is ideal for mass production and low-cost solutions.
Perfect Threads, Every Single Cycle
Our unscrewing mold ensures clean and accurate threading for molded parts. We keep every cycle stable, precise, and repeatable. Trust us for reliable threaded plastic parts.

Get A QuoteIncoming Material Inspection
At the factory, all materials are checked before molding. We typically confirm grade, moisture level, batch data, and other necessary parameters. We also filter out any materials that do not meet our unscrewing mold requirements.
In-process thread measurement
We also measure the critical dimensions of each part at every stage of the production line. Operators inspect the thread depth, width, and fit. We measure the threads during molding to ensure each part meets the required thread size.
Pitch and lead verification
We also check pitch and lead using fine thread gauges and other measuring tools. We ensure sizes and quality meet your project needs.
Cycle Time Consistency Checks
Considering the cycle time is crucial for every run. Each unscrewing mold has a specific cycle time to ensure it works correctly. This way, we can also reduce defects in the part.
SPC data tracking
For each batch, we record production data using SPC. The data shows trends in size, thread changes, and differences in cavity geometry. When necessary, we can make the required changes to the mold setup.
100% sample test Before Mass Production
Before mass production, we test every sample. We measure thread sizes, pitch, appearance, and fit. The factory can ensure you are getting the part as required.
