Introduction to the Vormek TrayShift VTC-500
In today’s factories, product variety is not a choice—it is a necessity. The market constantly demands packages in different sizes, weights, and shapes. While this diversity opens new market opportunities, it also brings challenges. One of the most critical bottlenecks is removing the mold currently installed in the tray sealer and replacing it with another—a task that, if not executed efficiently, can result in hours of line downtime.
Vormek’s tray sealers—whether from the General or Professional series—are designed to make mold changeover convenient. However, there is a significant difference between “possible” and “fast, safe, and systematic.” This is where the TrayShift VTC-500 comes in—a tool that not only accelerates mold changeover but also brings order to the process, enhances safety, and transforms mold maintenance into a systematic operation.
Introducing the TrayShift Technology
The TrayShift VTC-500 is a specialized mold changeover trolley designed for the transportation, storage, and rapid exchange of tray sealer molds. Based on 5S industrial organization principles, it provides a designated, standardized location for mold storage and turns the changeover process into a fast, safe, and hassle-free operation.
The name “TrayShift” accurately reflects its core function: rapid tool change. The technical slogan captures its design philosophy: Rapid Tool System and Safe Changeover.
Common Industry Challenges
In production facilities that use multiple molds for a single tray sealer, several challenges arise:
| Challenge | Description |
|---|---|
| Improper mold storage | Molds are scattered across the factory, disrupting production floor organization |
| Mold damage | Manual handling or improper placement causes impacts, scratches, and reduced service life |
| Long changeover time | Lack of a standardized system extends line downtime |
| Reliance on physical labor | In many factories, mold handling still depends on manual strength—difficult, time-consuming, and risky for both molds and operators |
| Difficult service and maintenance | Without proper equipment to hold the mold, access to various parts for cleaning, blade replacement, or element repair is limited—operators face both physical and operational constraints |
Technical Features
1. Full Stainless Steel Construction
The chassis and main body are constructed entirely from 304 stainless steel. This material provides excellent resistance to moisture, corrosion, industrial cleaning agents, and the demanding conditions of food production environments. All polymer components used are food-grade, making them suitable for hygienic food industry settings. Aluminum components are machined and then coated for surface protection, enhancing corrosion resistance.
2. Four‑Point Precision Height Adjustment System
One of the trolley’s most critical features is its four-point height adjustment capability. During mold changeover, the trolley rails must align precisely with the tray sealer rails.
Each leg is equipped with:
- Screw mechanism
- Height adjustment handle
- Position locking mechanism
Operators can independently adjust each leg’s height by turning the corresponding handle. This provides a height adjustment range of 100–150 mm, ensuring the trolley rails can be precisely aligned with the tray sealer rails at any height.
3. Simultaneous Multi‑Mold Storage Capacity
The trolley accommodates multiple molds simultaneously:
- Two molds on the lower tray section
- Two molds within the rail system
Operators can keep up to four complete mold sets organized and ready for use.
4. Two‑Tier Rail System with Rotary Mechanism
The central and upper sections feature a two-tier rail system. Each tier can hold one complete mold set. For quick access to different molds, the assembly is equipped with a rotary mechanism including:
- Industrial gearbox
- Power transmission system
- Manual control handle
Operators can rotate the handle 180 degrees to bring the second tier into the working position. The corresponding rail aligns precisely with the tray sealer rails, enabling rapid mold changeover.
5. Easy Mobility System
The trolley is equipped with heavy-duty industrial casters for easy movement around the factory floor. An ergonomic handle at the top allows operators to guide and maneuver the trolley with minimal effort.
6. Dedicated Storage for Auxiliary Components
In addition to the mold changeover system, the trolley includes designated spaces for auxiliary components. Dedicated locations on the base and side sections hold mold accessories and related equipment—supporting 5S industrial organization principles.
7. Ideal Work Platform for Mold Service and Maintenance
One of the trolley’s most important advantages is its role as a dedicated service and maintenance station for molds. When placed on the trolley, the mold is positioned at a standard working height, providing technicians with full access to all areas.
Operations That Can Be Performed on the Mold in This Position:
| # | Operation |
|---|---|
| 1 | Complete mold surface cleaning |
| 2 | Removal of film and container residues |
| 3 | Cutting blade cleaning |
| 4 | Blade condition inspection |
| 5 | Blade sharpening or replacement |
| 6 | Sealing mold inspection |
| 7 | Heating element performance check |
| 8 | Element replacement or repair |
| 9 | Thermocouple inspection and replacement |
| 10 | Internal wiring inspection |
| 11 | Preventive maintenance and major repairs |
The TrayShift VTC-500 is not just a transport device—it functions as a dedicated mold service and maintenance station.
Technical and Economic Benefits
| Category | Benefit | Description |
|---|---|---|
| Operational | Significantly reduced changeover time | Fast, efficient mold exchange |
| Eliminates risky handling | No reliance on manual labor or physical strength | |
| Increased line productivity | Reduced downtime between product runs | |
| Maintenance | Extended mold service life | Prevents impacts and damage during handling |
| Simplified service and repairs | Easy access to all mold areas | |
| Management | 5S and industrial organization compliance | Designated, standardized storage for each mold |
| Economic | Reduced maintenance costs | Regular, easy preventive maintenance |
| Reduced auxiliary equipment dependency | No need for cranes, forklifts, or hoists |
Mold Changeover Process with TrayShift VTC-500
| Step | Operation |
|---|---|
| 1 | Trolley is positioned in front of the tray sealer |
| 2 | Trolley rails are aligned and leveled with tray sealer rails (using height adjustment system) |
| 3 | The active mold is removed from the machine and transferred onto the empty trolley rail |
| 4 | The handle is rotated 180 degrees to bring the new mold into position |
| 5 | The new mold is gently pushed along the rails into the tray sealer |
| 6 | The mold is locked in place using positioning pins |
| 7 | Electrical and pneumatic connections are attached |
| 8 | The machine is ready for production with the new mold |
