Hengyao – Wholesale Office Chair Production Process

1. Corte de tubos
Utilizamos tubos metálicos de alta calidad como materia prima principal para garantizar que la estructura básica de cada silla de oficina comercial sea resistente, estable y adecuada para un uso B2B repetido.

2. Perforación de un agujero
Mediante equipos de corte CNC de alta precisión, los materiales de las tuberías se cortan con exactitud según los planos de diseño, lo que garantiza que el error dimensional de cada sección se mantenga dentro de un margen extremadamente reducido.

3. Tubo mezclador
Realizar cortes de precisión secundarios y recorte de bordes en los tubos, eliminando rebabas y bordes y esquinas sobrantes, para que la superficie de los componentes quede lisa y plana.

4. Soldadura manual
De acuerdo con el diseño estructural de la silla, se taladran orificios con precisión en los puntos indicados del tubo, lo que facilita la posterior fijación con tornillos y el montaje de los componentes.

5. Pulido
Los componentes están totalmente soldados para garantizar que cada unión de soldadura sea firme y no presente huecos, lo que mejora la resistencia general del bastidor.

6. Eliminación de impurezas
Realiza un pulido minucioso del bastidor soldado para eliminar las marcas de soldadura y las superficies rugosas.

7. Con recubrimiento en polvo
Mediante la tecnología de pulverización electrostática de polvo, respetuosa con el medio ambiente, se forma una capa protectora uniforme sobre la superficie del marco metálico.

8. Vetas de madera
Tras el recubrimiento en polvo, el bastidor se somete a un tratamiento de curado a alta temperatura, lo que hace que el recubrimiento se adhiera firmemente, dando como resultado un bastidor acabado que es a la vez estéticamente atractivo y protector.

9. Control de calidad
El armazón homologado se monta de forma profesional junto con el asiento, el respaldo y el resto de accesorios para completar el montaje de la silla de oficina.

10. Montaje del bastidor
Utiliza materiales de embalaje protectores de varias capas para amortiguar y envolver las sillas de oficina terminadas.

11. Carga del contenedor
Las sillas de oficina terminadas se almacenarán de forma ordenada y estarán listas para su envío a clientes de todo el mundo en cualquier momento.

How to Choose 998-B for High-Back Mesh Office Chair Projects
998-B should be evaluated as a high-back mesh office chair for project and distributor use, not as a simple low-price task chair. Before confirming a bulk order, buyers should check whether the high-back size, 3D headrest range, and height adjustable lumbar support match the target user group.
The sample check should include mesh rebound, seat new foam support, 3D flip-up armrest movement, base balance, caster rolling, carton protection, and sample-to-bulk consistency. These details matter because a premium-looking chair can still create complaints if support points, packing, or assembly details are not confirmed early.

Check High-Back Profile, Headrest Fit, and Lumbar Height
The high back is the main reason to choose 998-B. During sample review, ask users of different heights to test whether the 3D headrest can be positioned behind the neck without forcing the head forward. Then adjust the lumbar support through its available range and check whether it reaches the lower-back area without creating a hard pressure point.
Record the approved headrest and lumbar positions with sample photos or a short function video. This gives project buyers a clearer reference when checking whether bulk production matches the approved sample.

Check Mesh Tension, Seat Foam, and Daily Office Comfort
Reliable choice: mesh support, headrest fit, and seat comfort
For office projects, comfort problems often come from weak mesh tension, poor seat support, or inconsistent bulk production. Compare the approved sample with pre-shipment photos and function-check videos before confirming loading.
Avoid pitfalls: weak mesh, loose headrest, unstable base, or poor carton protection
For distributor and project orders, ask for close-up checks of mesh tension, headrest adjustment, screw matching, gas lift movement, mechanism function, base balance, caster rolling, spare parts, labels, and carton marks.

Check Gas Lift, Mechanism, Base, and Castors
Test the height adjustment through repeated up-and-down movement, then check that the mechanism operates smoothly without unusual play or noise. Inspect the connection points between the seat, mechanism, gas lift, and base before the chair is packed. The base should sit level on a flat surface, and the castors should roll without dragging or wobbling.
Ask for a short function video and pre-shipment inspection photos showing the under-seat mechanism, gas lift, base, and castors. A high-back chair may look premium in photos, but unstable moving parts can create the most expensive after-sales problems.

Check 352 pcs/40HQ Loading and Project Cost Control
998-B uses a 59 x 37 x 71 cm packing size with a 352 pcs/40HQ loading reference. Before approving the quotation, confirm the carton construction, hardware-kit layout, assembly manual, carton marks, spare-parts plan, and whether mixed-model loading is needed.
The buyer should also confirm the loading plan and shipment documents in writing before production starts. This makes it easier to compare freight, landed cost, warehouse handling, and project delivery timing without relying only on a headline unit price.

Cómo cuidar tu silla de oficina
Follow this care guide to keep the 998 height adjustable mesh office chair clean, stable, and ready for staff office, manager room, and shared workspace use.
Limpieza periódica
Limpia la superficie de malla o tela con un paño suave o un limpiador adecuado para tejidos, y evita los productos químicos agresivos. En el caso de uso en oficinas comerciales, comprueba periódicamente el pistón de gas, los tornillos, los reposabrazos, las ruedas y la unión de la base para garantizar la estabilidad de la silla de oficina durante su uso diario.
Revisa periódicamente los tornillos de fijación
Over time, the screws might loosen. So, let’s check if they are loose.
Evita la luz solar directa
Prolonged direct sunlight may fade mesh or fabric surfaces. For showrooms or project sites, keep chairs away from long direct sunlight where possible.
El uso adecuado de la silla de oficina
Utiliza la silla únicamente para el trabajo de oficina habitual en posición sentada. No te subas a la silla, no te sientes en los reposabrazos, no saltes sobre el asiento, no sobrecargues el mecanismo ni utilices la silla como escalera.
Mantenimiento de la función de elevación y rotación
Every month, apply a small amount of silicone-based lubricant (do not use engine oil) at the rotating shaft and the pedal ring to ensure smooth operation.
Avoid frequent violent lifting and lowering, and single-point heavy pressure to prevent damage to the air pressure rods.
Metal (forja / acero inoxidable / galvanizado)
Dry off the water stains. In damp environments, apply a thin layer of anti-rust oil / sewing oil regularly.
Remove rust: For small rust spots, soak them in oil and then wipe them off. For severe rust, seek professional treatment.
