Why is glue dispensing uneven?

This is mainly caused by unstable storage flow pressure or air pressure. The inlet pressure should be set 10-15psi lower than the factory minimum, and the rubber valve control pressure should be at least 60psi.

What to do if flow velocity is too slow?

Change the pipe from 1/4 to 3/8 if the flow velocity is too slow. The shorter the pipe, the better, provided there are no other requirements.

How to avoid air in the fluid?

Excessive fluid pressure and short valve opening time may lead to air infiltration. Use conical needles and reduce fluid pressure to solve this.

How to prevent instant glue from blocking valves?

This is caused by heavy moisture and recycled instant glue. Use new glue, wash pipes with dry acetone, ensure air is dry, and add a filter between plant air pressure and the valve.

How to handle UV glue to avoid bubbles?

Use black pipelines. Do not add new UV glue to old UV glue in the pressure tank; drain off old glue first, as old UV glue produces bubbles that lead to uneven dispensing.

AI-Powered supplier vetting

SummaryThe supplier is a Guangzhou-based limited trading company in the manufacturing sector, offering glue-dispensing and related equipment. It reports broad customization and ODM capabilities, new product development within the past year, raw-material traceability, and 100% finished-product inspection supported by three quality inspectors. Manufacturing capacity is supported by valid contracts with associated subcontractors and in-stock capability, while lead time is stated as within 15 working days in both peak and off-season periods. Written procedures exist for supplier-service assessment, corrective and preventive actions, and customer complaints. However, no overseas warehouse, showroom, agents, branches, or overseas service countries are reported. Certification holdings and customer cases are not provided. Financial data is excluded from this assessment.

Supplier typeThe supplier is identified as a limited company located in Huangpu District, Guangzhou, with a stated company nature of trading company. Its business scope includes goods and technology import/export, while its offered products are glue-dispensing and related machines.

After-Sales capabilityThe supplier has written and followed procedures for service-capability assessment, corrective and preventive actions, and customer complaints. It also reports in-stock capability, but has no overseas warehouse, showroom, agents, branches, or overseas service countries, which limits documented international service coverage.

The supplier reports valid manufacturing contracts with each associated subcontractor, in-stock capability, 100% finished-product inspection, three quality inspectors, and lead times within 15 working days in both peak and off-season periods.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are reported consistently across the R&D and quality-related information.

Product Q&A

Q:Do you offer overseas service?

We do not have an overseas service center, but we can offer overseas service if the customer requires it. An engineer will provide face-to-face service.

Q:How does your factory handle quality control?

We assure a 1-year warranty for the main parts and offer spare parts for backup. Please check with the sales engineer for details.

Q:What are your payment terms?

Normally, 30% advance by T/T and the balance is paid off before delivery.

Q:Are you a factory or trading company?

We are a factory with SGS certification and more than 20 patents, cooperating with different customers covering about 40 countries for over 15 years.

Q:Why does the glue dispenser always drop?

Drops may happen due to low glue concentration, high air pressure, or large needle diameter. Narrow needles cause back pressure. Using conical needles or adjusting air pressure can solve this.
