Why are hollow brick holes collapsed and green bricks soft and deformed?

Two main reasons: excessively high mud moisture or insufficient extrusion pressure. Reduce the water content of raw materials and check the machine's transmission system to restore standard extrusion pressure.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company, but the information also describes extensive industrial equipment, brick-kiln engineering, OEM/ODM services, and broad customization capabilities. It reports exports representing 71%–90% of total sales, five years of exporting experience, and overseas agents or branches. Customer complaint handling has a clear procedure with records, while quality assurance and raw-material traceability are stated. However, several management controls lack written records, including finished-product inspection, supplier-service assessment, corrective/preventive actions, and some quality-control capability records. Innovation evidence is limited: ODM and customization are available, but no new product was reported in the past year and no SDK is available. No evidence establishes certifications, overseas warehouses or showrooms, or participation in offline trade shows.

After-Sales capabilityThe Xinxing brand is described as having recognized after-sales service, and the supplier has a clear customer-complaint procedure with follow-up records. It also provides services through overseas agents or branches, but has no overseas warehouse or showroom and has not participated in offline trade shows; the overall breadth of after-sales coverage is therefore only partially evidenced.

Production capacityThe information lists numerous industrial manufacturing and processing capabilities, including cutting, cranes, rolling, milling, boring, lathes, planing, and welding, and describes brick-extrusion equipment exported internationally. Quality assurance and raw-material traceability are stated, but finished-product inspection and some quality-control records are only instructional and not documented.

Customization capabilityThe supplier explicitly provides customization from samples, customization from designs, full customization, minor customization, and flexible customization, and also offers ODM services. These statements directly support broad customization capability.

Client casesThe company states that its Xinxing brand brick-extrusion equipment is exported to over thirty countries and regions, with exports accounting for 71%–90% of total sales and five years of export experience. It also reports OEM service for well-known brands and overseas agents or branches, but no named customers or independently verifiable case details are provided.

Product Q&A

Q:What kinds of raw materials can brick making machines process?

It can process clay, shale, coal gangue, fly ash, construction waste soil, mine tailings and other solid waste materials. It can produce solid bricks, hollow bricks, perforated bricks, permeable bricks and decorative bricks by changing molds.

Q:Can you customize brick molds according to local brick sizes?

Yes. We support custom molds of different sizes, hole shapes and surface textures to match local building standards

Q:What supporting kiln equipment matches this brick extruder?

It is compatible with tunnel kilns and annular kilns, suitable for both one-time setting and two-time setting brick production lines.

Q:Why do green bricks have air holes on the surface?

The vacuum system fails to exhaust air fully. Reasons include insufficient vacuum pump oil, emulsified oil, leaking vacuum pipes or blocked filter screens. Check and maintain the vacuum system regularly.

Q:What causes cracks, delamination on mud strips and green bricks?

Main causes: insufficient vacuum degree, uneven moisture of raw materials, worn dies or unreasonable die chamfer. Check vacuum sealing, adjust raw material mixing time or replace the die.
