Do you provide custom-designed filter discs for specific machinery?

Yes, we offer custom engineering for diameter, thickness, hole patterns, mesh layers, and connections to fit various filter housings and OEM equipment.

How often should melt filters be replaced or cleaned?

This depends on polymer contamination levels, throughput, and allowable pressure drop. Generally, filters are cleaned or replaced when pressure increases by 20-30% above baseline.

What is the lead time for standard and custom filter discs?

Standard sizes are typically available in 3-5 days. Custom designs may require 7-15days depending on complexity and order quantity.

Do you offer trial samples for testing?

Yes, we can provide sample discs for evaluation in your production line, subject to feasibility and quantity agreements.

What packing and shipping methods do you use for international orders?

Filters are carefully packed in anti-corrosion materials and shipped via air or sea freight with full export documentation, including material certifications.

AI-Powered supplier vetting

SummaryPujiang HG Filter presents itself as a direct manufacturer of mesh filters and filter mesh, with two production lines, 13 employees, ISO 9001 certification, and stated customization capabilities. Its finished-product inspection instructions are reportedly implemented uniformly, and export sales account for 51%–70% of total sales. However, quality-control staffing is limited, production-batch quantity reconciliation is not ongoing, and documented records are absent for service-capability assessments, corrective/preventive actions, and complaint handling. OEM service for popular brands is indicated, but no SDK is available and R&D experience is under five years. Overseas warehouses, showrooms, agents, branches, and offline trade-show participation are not available. Financial figures, export-license status, customer cases, and environmental and fire-drill documentation are not sufficiently evidenced.

Supplier typeThe supplier identifies itself as a direct manufacturer and offers mesh filter and filter mesh products. Its stated business scope includes textile special equipment sales and licensed import/export and technology-import activities, while its ownership is a limited company with no larger-company affiliation.

CertificationsThe supplier reports holding ISO 9001 certification. No other certification is identified in the provided information.

Production capacityThe supplier reports direct-manufacturer status, two production lines, cutting/lathe/drilling facilities, 13 total employees, and uniformly followed finished-product inspection instructions. Counterbalancing limitations include one quality assurance/control inspector and no ongoing quantity reconciliation for each batch or bulk production.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. This is supported by stated engineering capability, although the slices do not provide project examples or performance records.

Product Q&A

Q:What is your MOQ?

Usually, it is 100PCS, but if we have other orders together, can help you with small QTY also.

Q:What materials are melt filter discs made from?

They are commonly manufactured from stainless steel (e.g., 304, 316), high-grade alloy steels, or specialty metals capable of withstanding high temperatures and corrosive polymer melts.

Q:What filtration ratings or micron sizes are available for polymer melt filters?

Filtration ratings typically range from 5 microns to 500 microns, depending on application requirements. Common sizes for fine filtration are between 10 and 40 microns.

Q:Can melt filter discs be cleaned and reused?

Yes, most metal filter discs are designed for repeated cleaning using thermal, chemical, or ultrasonic methods to restore performance and extend service life.

Q:How do I choose the right filter disc for my polymer application?

Selection depends on polymer type, operating temperature, pressure, required filtration fineness, and chemical compatibility. Consult with our engineers for specific recommendations.
