How to Verify Metal and Glass Ink Adhesion Before Production

Before scaling up a printing job, test ink on samples that closely match the final metal or glass component. Use the planned surface preparation, printing method, and production process, then review both adhesion and print appearance. The available information for Shichuangli PP ink does not specify a metal- or glass-specific test procedure or a pass/fail standard, so suitability should be confirmed for the intended application.

Build a Representative Sample Trial

A sample is useful for a production decision only when it reflects the material and process that will be used at volume. Print on the actual metal or glass substrate, with its intended surface condition, and follow the planned production settings. Keep the trial conditions consistent across samples and record what was used.

After processing, examine whether the print remains attached and whether its appearance is consistent. Keep accepted samples as references for production. If the substrate, surface preparation, printing method, or process changes, evaluate the revised combination before proceeding.

What the Product Information Does and Does Not Confirm

Shichuangli PP ink is identified as item SCL-00YM, supplied at a net weight of 1,000 g per piece. Listed colors are black, white, red, blue, yellow, and green. The stated printing methods include screen printing, pad printing, offset printing, and screen flexographic printing.

The product information names shampoo bottles, cosmetic bottles, stationery products, and batteries among its applications, but does not specifically identify metal or glass substrates. It also does not provide curing parameters, a durability-test method, a metal/glass adhesion protocol, or numerical acceptance criteria. Ask the supplier to confirm suitability and agree on application-specific evaluation conditions rather than treating unlisted details as product specifications.

Pre-Production Review

Applications and Supporting Information

Shichuangli describes printing work across consumer goods, electronics and household appliances, automotive parts, and packaging. Its listed PP ink applications include packaging and consumer-product contexts such as shampoo and cosmetic bottles. These examples provide context for the company's printing work, but do not establish adhesion performance on every metal or glass surface.

The company profile lists IECEx certificate IECEx PTB 05.0006X for an electromagnetic valve and trademark registrations related to printing equipment. Neither is presented as certification of PP ink adhesion on metal or glass. Similarly, a case involving a Saudi Arabian hotel-product distributor describes screen printing, heat-transfer printing, and hot stamping on different materials; it is not a documented adhesion test for this ink.

Frequently Asked Questions

Is adhesion on metal and glass confirmed by the supplied product data?

No. Metal and glass are not specifically identified as applicable substrates, and no substrate-specific test results are provided. Validate the ink on the actual materials before production.

Which printing processes are listed?

The listed options are screen printing, pad printing, offset printing, and screen flexographic printing. Confirm which method is appropriate for the part and planned production conditions.

What needs to be settled before ordering for volume?

Confirm the substrate and surface condition, printing method, process conditions, inspection approach, and acceptance criteria with the supplier. The available data does not define a test procedure or numerical pass threshold.

Recommendation

Move from samples to volume only after evaluating the intended metal or glass part with the planned printing process, documenting adhesion and appearance, and agreeing with the supplier on application-specific acceptance criteria. Shichuangli states that it offers OEM/ODM customization and technical training, and its profile describes a factory training base of more than 1,600 square meters.
