A 2CAV 6-comp box mould is used for portion-control meal trays where separate food zones, stable stacking, and reliable lid fit are all required. For buyers, the mould is not simply a six-compartment shape; it is a production tool that must keep divider walls, outer rim, base flatness, and demolding behavior consistent across continuous runs.
This type of tray is commonly used for takeaway meals, prepared food, institutional catering, and airline or school lunch packaging. The tooling should be evaluated around the final food packaging workflow, including filling, sealing, stacking, transport, and consumer opening experience.
Filling Balance Across Compartments
Six-compartment trays have multiple ribs and flow restrictions. If melt flow is not balanced, one compartment may overpack while another shows short shots, weak corners, or uneven wall thickness. Buyers should ask how the mould design controls gate location, venting, flow length, and cooling around the divider walls.
The selected resin and target part weight should be reviewed early. Thin-wall PP trays require enough injection speed and cooling capacity to fill cleanly without adding unnecessary weight. Machine matching is part of the mould decision, especially for high-output food packaging lines.
Divider Strength, Rim Sealing, and Stackability
The divider ribs must be strong enough to hold food separation without creating sink marks or ejection problems. At the same time, the outer rim must match the lid and remain flat after cooling. Poor rim control can create leaks, while weak dividers can deform during filling or transport.
Stackability should be checked with real tray samples, not only in CAD. Buyers should test nested trays, carton packing, robotic pickup, and whether trays separate cleanly during production. These details affect labor cost and line stoppages after the mould enters daily use.
Buyer Acceptance Checks
Before accepting a 2CAV 6-comp box mould, request samples from each cavity, part weight records, key dimension reports, continuous trial data, lid-fit results, stacking tests, and photos of any post-trial corrections. Acceptance should also cover spare parts and maintenance access for wear areas around ribs and ejection components.
A focused RFQ should include tray and lid drawings, resin grade, wall thickness target, machine details, cavity preference, output target, automation method, and food-contact requirements. With this information, the supplier can propose a tray mould that supports production economics instead of only matching the visible tray shape.
