Product Description
12-Cavity Rectangular Clamshell Food Container Thermoforming Mold | Custom Aluminum Tooling
Product Overview
This custom aluminum thermoforming mold is designed for rectangular clamshell-style food containers. The pictured tool features 12 rectangular cavities arranged in a 3 × 4 layout, with shaped corners and a defined perimeter profile. Cavity dimensions, rim details and mounting interfaces can be developed around the approved container drawing or sample and the target thermoforming machine.
For packaging manufacturers, the tooling design needs to account for container depth, corner transitions, rim geometry and the required cutting line. Before production, the cavity arrangement and mold configuration should be checked against the sheet width, material specification, forming area and machine station setup for the intended rectangular container.
Engineering Focus
Rectangular clamshell tooling must reproduce the container outline and perimeter details while fitting the available machine space. Cavity spacing, forming depth, trimming position and mold installation dimensions should be coordinated as one tooling design rather than treated as separate items.
01
12-Cavity Rectangular Layout
The pictured mold plate contains 12 cavities arranged in three columns and four rows. Final cavity spacing and edge clearances should be confirmed against the machine forming area and sheet layout before the tooling drawing is approved.
02
Defined Rim and Corner Geometry
The cavity outlines include shaped corners and a stepped perimeter. These areas should be matched to the approved container sample or drawing so the finished pack retains the intended edge profile and lid or closure interface where applicable.
03
Forming and Cutting Coordination
The cavity layout can be coordinated with the selected trimming method and the required cut line around each container. In-mold cutting or a separate cutting station should be specified according to the actual thermoforming machine and production process.
04
Machine-Specific Mold Base
Mold base dimensions, mounting points and station clearances need to match the target equipment. Machine drawings and installation details help the engineering team confirm the interface before manufacturing begins.

Frequently Asked Questions
Can this mold be customized for a rectangular clamshell container?
Yes. The cavity dimensions and perimeter profile can be developed from your approved drawing or sample. The final design depends on container depth, material, forming method and the specifications of the target machine.
How is the 12-cavity layout confirmed?
The pictured plate shows 12 cavities in a three-column, four-row arrangement. Final spacing and edge clearance should be checked against the machine forming area and sheet width before the mold design is released.
Which sheet material can be used with this mold?
Material suitability should be confirmed from the intended sheet type and gauge, together with the forming temperature and machine setup. Please provide these details during the design review.
What machine information is needed before ordering?
Please provide the machine brand and model, forming area, mold-base or installation drawings, and whether forming and cutting take place in one station or separate stations.
