GS 5T Bench-Top Catheter Overmolding
The Pezo GS-5T is a compact, bench-top injection molding press built for teams who need real molded parts without the cost or complexity of full-scale molding equipment. It runs on 120V power and standard shop air, switches materials quickly with zero waste, and is ideal for prototype handles, insert molding, and low-volume builds. Durable, portable, and simple to operate—the GS-5T gives R&D and manufacturing teams a fast, low-risk way to mold production-quality thermoplastics.

GS-5T
The GS-5T is purpose-built for quick iteration and small-batch molding. Its pneumatic ram, simple controls, and small footprint make it easy to place directly on an ELEVT™ workstation or in tight cleanroom spaces. A single operator can switch materials in minutes and run insert molds up to 0.25 oz.
Key Benefits:
- Ideal for R&D, prototyping, and short-run manufacturing
- Quick material changes with no wasted resin
- Simple setup—120V AC and standard 125 psi shop air
- Supports all common thermoplastic materials
- Proven reliability with units running daily for 10+ years
GS-5T Specifications:
- Size: 24" H × 17" W × 25.5" D
- Weight: 230 lbs
- Injection Pressure: Up to 10,000 psi at ram
- Shot Size: Up to 0.25 oz
- Clamp Pressure: 5 US tons (air-over-hydraulic)

GS-5T Plus
The GS-5T Plus builds on the GS-5T platform with higher injection pressure and an integrated PLC/HMI control system—ideal for teams who want tighter process control and repeatability while staying within a bench-top format.
GS-5T Plus Enhancements:
- Higher injection pressure (14,000 psi at ram)
- Integrated PLC & touchscreen HMI
- Store and recall up to 30 molding recipes
- Same 0.25 oz shot size and 5-ton clamp

Frequently asked questions
What kinds of parts can the GS-5T and GS-5T Plus mold?
Both machines support all common thermoplastics and are ideal for small, single-cavity parts up to 0.25 oz—such as catheter handles, strain reliefs, insert-molded components, and R&D prototypes.
What’s the difference between the GS-5T and GS-5T Plus?
The GS-5T Plus delivers higher injection pressure, PLC/HMI controls, and recipe storage for more repeatable processing. The GS-5T is simpler and lighter, perfect for quick-change R&D and prototyping.
Do I need special utilities or a dedicated molding cell?
No. Both machines operate on 120V AC and standard 125 psi shop air. They can be placed directly on an ELEVT™ workstation or benchtop in a cleanroom.
Can Pezo build the tooling?
Yes. Pezo designs and machines single-cavity tools, inserts, and fixtures in-house. You get a complete, integrated molding setup tuned to your part and process.
When should I move from a GS-5T to a full-scale molding press?
When volumes grow or you need multi-cavity throughput. The GS-5T platform is perfect for development, low-volume production, and pilot lines—while larger presses (Arburg, Boy, etc.) are better for high-volume programs.
