Precision Automated Unscrewing
Optimized for precision-threaded parts like medical connectors and specialized caps, our unscrewing mold technology ensures zero-defect production by automating the release process.
By synchronizing high-torque drive systems—such as racks, hydraulics, or motors—to precisely “unscrew” parts during ejection, we eliminate the risk of thread stripping and deformation. This high-speed, automated solution guarantees absolute dimensional consistency while significantly reducing scrap rates and operational costs for high-volume manufacturing.

The Ultimate Guide to Custom Auto-Unscrewing Mold Solutions by GBM
In high-volume production of internally or externally threaded plastic components, precision and cycle time are critical. At GBM, we leverage over 20 years of mold-making expertise to simplify the complex process of designing and manufacturing high-precision automatic unscrewing molds. Equipped with advanced Japanese and Taiwanese machining centers, we provide tailored, durable tooling solutions that ensure perfect thread profiles, stable production, and reduced cycle times for Tier-1 automotive, medical, and electronics industries.

What Is an Automatic Unscrewing Mold and Why Does It Matter for High-Volume Production?
An automatic unscrewing mold is a specialized injection tooling system designed with integrated drive mechanisms. Instead of manual ejection, these gears and drives automatically rotate to unthread and release molded plastic parts directly during the mold-opening cycle.
The Manufacturing Impact: Manual thread unwinding introduces inconsistencies and slows down production. Automatic unscrewing molds eliminate manual intervention, slashing cycle times and preventing the structural damage (such as thread stripping) often seen in delicate part ejection. For mass production, this mechanism is the definitive solution for maximizing output stability and minimizing the cost-per-part.
Selecting the Right Drive System for Your Threaded Parts
At GBM, we don’t use a one-size-fits-all approach. The efficiency of an unscrewing mold depends entirely on matching the drive mechanism to the part’s geometry and production environment. The three primary systems include:
Hydraulic Cylinder / Rack and Pinion: Engineered for applications requiring long strokes and substantial power. Best suited for large-scale molds and heavy-duty industrial components.
Electric Servo Motors: Delivers frictionless, high-precision rotation. Because it eliminates oil risks, this system is our standard recommendation for cleanroom environments, medical devices, and sensitive electronics.
Mechanical Mold-Opening Drives: Harnesses the injection machine’s inherent opening force to actuate the gears. A highly efficient, low-maintenance choice for parts with shorter thread lengths.
Manual Inserts vs. Fully Automatic Unscrewing: A Data-Driven Choice
Hand-loaded inserts or manual unscrewing can reduce initial tooling costs, making them viable for rapid prototyping or low-volume runs.
However, when production scales beyond 100,000 units, manual processing becomes a bottleneck. A fully automatic unscrewing mold shifts the ROI equation by delivering:
A drastically reduced Cost-Per-Unit (CPU)
Consistent, accelerated cycle times
Elimination of human error and manual handling defects
Critical DFM Requirements for Threaded Plastic Components
Manufacturing reliable threaded parts requires rigorous Design for Manufacturability (DFM). Based on our extensive tooling experience, we focus on three critical engineering factors:
Optimized Thread Profiles: Redesigning sharp internal corners into radiused edges to eliminate stress concentrations and prevent premature part failure.
Anti-Rotation Features: Engineering specific locking features into the part design to ensure the component remains completely stationary while the mold core spins during the ejection phase.
High-Performance Material Processing: Threaded parts are prone to shrinkage and deformation. GBM engineers specialize in controlling the dimensional stability of demanding engineering resins, including PEEK, PPSU, and PA+GF.
The GBM Advantage: Precision Tooling Without Compromise
Unscrewing molds fail when mechanical synchronization is poor.
With over 20 years of dedicated injection molding expertise and a facility equipped with advanced Japanese and Taiwanese CNC machining centers, GBM achieves gear and core tolerances as tight as 0.01mm. Our stringent quality control is why Tier-1 automotive suppliers like Yanfeng trust us to deliver complex, durable tooling that performs right the first time.

Frequently Asked Questions!
For parts like bottle caps and pipe fittings with multi-threaded designs or high-volume production requirements, traditional manual de-threading is not only inefficient but also prone to damaging threads. Our fully automated de-threading solution employs high-precision drive mechanisms to ensure every rotation is smooth and seamless.
We specialize in hydraulic motor and gear-driven designs, offering custom mold steel solutions with exceptional wear resistance tailored to your production demands (e.g., over 500,000 cycles). We pursue optimal cycle times while guaranteeing absolute consistency in thread dimensions.
We select hydraulic motors, electric motors, or machine tool rack drives based on product structure. For high-efficiency production, gear drives provide more stable synchronization.
We utilize premium mold steels like S136 or H13, combined with specialized coating treatments. This ensures thread profiles remain sharp and free from chipping even after tens of thousands of cycles.
Through optimized water cooling and precise rotational speed control, we minimize ejection time, achieving efficiency 2-3 times higher than manual or basic mechanisms.
Absolutely. Our design team possesses extensive experience in precisely calculating thread pitch and rotation cycles for synchronized multi-start thread ejection.
