METAL LID SEALING EQUIPMENT
EVA, PVC and PU gasket production machines
Three machine platforms matched to pre-formed EVA strip, one-component PVC compound and two-component PU foam-in-place processes.
EQUIPMENT RANGE
Three processes for different gasket systems
EVA automatic gasket lining machine
Feeds pre-formed EVA strip, inserts it into the groove, cuts it and heat-welds the joint without an oven.
PVC one-component dispensing machine
Meters a continuous PVC bead into metal lid grooves before controlled oven curing.
PU two-component dispensing machine
Meters and dynamically mixes two PU components for room-temperature foam-in-place gaskets.
PROCESS MATCHING
Choose equipment after the sealing process is fixed
The machine cannot be selected from lid diameter alone. Start with the sealing material and curing method, then match the lid path, groove, bead or strip dimensions, production rate and factory utilities. The compound or EVA strip and the machine should be sampled together because material handling and process settings determine the finished gasket.
For integration, confirm lid feeding and discharge orientation, recipe changeover, inspection method, oven capacity where applicable, cleaning method and the interface with the customer production line. Reference specifications on the detail pages are configurable ranges, not a final machine proposal.
| Equipment | Sealing material | Core process | Typical reason to select |
|---|---|---|---|
| EVA automatic gasket lining machine | EVA roll stock | Feed, groove insertion, hot-knife cut and heat-welded joint | Pre-formed gasket process with no curing oven |
| PVC one-component dispensing machine | 1K PVC compound | Metered bead dispensing followed by oven cure | High-volume metal lid lines with a controlled baking process |
| PU two-component dispensing machine | 2K PU compound | Component metering, dynamic mixing and 3-axis dispensing | Room-temperature curing and programmable gasket paths |
Recommended project sequence
Send drawings and representative lids first. Jinyu reviews the groove and material, prepares a sample process, confirms the gasket result, and then defines heads, motion range, output, controls and line interfaces. Acceptance criteria should include bead or ring dimensions, cycle time, repeatability and the agreed sealing test.
SEALING EQUIPMENT FAQ
Questions before machine configuration
Which machine is used for pre-formed EVA gaskets?
The EVA automatic gasket lining machine feeds continuous EVA strip, places it in the lid groove, cuts the strip and heat-welds the joint. It does not dispense liquid compound.
Does a PVC dispensing line require an oven?
The one-component PVC process normally requires a controlled oven cure after dispensing. The required temperature and dwell time must be validated with the selected compound and lid.
What information is required before configuring a sealing machine?
Provide lid drawings and samples, gasket or bead dimensions, material, line speed, available space, utilities, upstream and downstream handling, test method and target output.
