TL;DR

YisenPulp operates 36+ production lines across 18,000??in Guangdong, China. Daily capacity: 8-12 tons of finished molded pulp packaging. Precision: 8mm relief depth at 0.2mm tolerance. We stock bagasse, bamboo, and FSC wood pulp in-house and can switch between materials within 2 hours. Quality control runs 7 checkpoints from pulp slurry to final packaging. Lead time: 72 hours for samples, 15-25 days for production orders.

We get asked the same questions from every serious buyer. How big is your factory? How many lines do you run? Can you handle my order volume? Do you have quality control? What's your lead time?

Rather than sending PDF brochures one by one, here's a transparent tour of our operations ??the real numbers, the real processes, and what you can expect when you work with YisenPulp.

Factory Overview

Our production facility is located in Dongguan, Guangdong Province ??the heart of China's manufacturing belt, 90 minutes from Shenzhen and Hong Kong ports. The 18,000??facility is divided into four zones:

  • Zone A ??Pulp Preparation: Hydrapulpers, defibering tanks, slurry blending, and consistency control. Raw material warehouse adjacent.
  • Zone B ??Forming & Pressing: 36 forming stations (wet-press and thermoforming). This is where the molding happens.
  • Zone C ??Drying & Finishing: Multi-zone conveyor drying ovens, trimming, quality sorting, and packaging.
  • Zone D ??Tooling & Mold Shop: In-house mold design and fabrication. CNC machining, EDM, and surface finishing.

Quality Control: 7 Checkpoints

Every order passes through these gates:

  1. Raw material inspection ??Fiber length distribution, moisture content, contamination check on every batch
  2. Slurry consistency test ??Viscosity, fiber concentration, drainage rate ??adjusted before every production run
  3. First-article inspection ??Dimensional check, weight, visual surface review ??100% measured before production continues
  4. In-process QC (every 2 hours) ??Sample from each mold cavity checked for wall thickness, density, and edge quality
  5. Dried product inspection ??Moisture content (target: 6-10%), structural integrity, flatness
  6. Final visual inspection ??100% of finished products visually inspected for defects: cracks, thin spots, surface imperfections
  7. Packaging & shipping QC ??Packing verification, moisture barrier confirmation, pallet integrity, label accuracy

All inspection data is logged and traceable to production batch. We maintain ISO 9001:2015 certification and undergo annual external audits.
