2. Quality Control During Production:
(1). Quality Control Starts Right From Raw Material Procurement.
(2). The Full Traceability of Both Raw Materials and Finished Dished Head Serves As The Primary Guarantee for Stable Quality.
(3). Every Production Step is Guided by a Dedicated Production Process Sheet, Which is Generated by Our Technical Department for Each Individual Order.
(4). The Production Process Sheet Compiled in Accordance with Customers’ drawings, Product Specifications and Detailed Technical Requirements, These Sheets Act as The Official Production Standards for Workshop Staff.
(5). All workers Must Strictly Follow The Process Sheets during manufacturing and sign their names next to each procedure they are responsible for.
Once production is finished, all process sheets are returned to the technical department for digital filing and uploaded to our internal database.
3. Certificates:
We are certified under ASME and PED (Pressure Equipment Directive) standards, demonstrating our capability to manufacture pressure components for global markets including Europe and North America. These certifications ensure our products meet stringent requirements for safety, reliability, and performance in pressure vessel and critical industrial applications.
4. Frequent Asked Questions(FAQ):
(1) Are you a factory or a trading company?
Henan Guojiang Precision Formed Head Co., Ltd. is a dedicated manufacturing facility specializing in the production of dished ends (ellipsoidal, torispherical, hemispherical, and custom-formed heads) for industrial applications.
(2) Is your quality control system reliable?
Our production system operates under a structured quality management workflow with strict process control. Each manufacturing order is released only after technical review and process validation by the Production Technology Department.
All fabrication stages are governed by controlled process sheets (route cards), ensuring traceability and compliance at every step, including forming, heat treatment (if required), machining, and inspection. Batch-level quality control is implemented to ensure dimensional accuracy, surface integrity, and compliance with applicable technical specifications, including high-precision applications such as MRI and magnetic resonance equipment.
(3) Do you support customization?
Yes. We provide full customization services for non-standard and engineered dished heads. Production is carried out strictly according to client-supplied technical drawings, material specifications, design codes, and dimensional requirements. Engineering support is available for specification clarification prior to quotation and manufacturing.
(4) Do you strictly control delivery schedules?
Yes. Delivery control is integrated into our production planning system. Each order is assigned a defined manufacturing schedule based on process routing, material availability, and workload balancing.
Lead times are calculated prior to production release and are strictly managed through internal scheduling controls to ensure on-time delivery in accordance with confirmed production plans.
