About us
A vertically integrated injection device plant in Zhengzhou
Meishijie Digital Technology (Henan) Co., Ltd. develops, produces and sells injection devices and related consumables, with the whole manufacturing chain kept in house.
Company overview
A vertically integrated injection device plant
Around 15,000 m² of workshop space covers mold making, injection molding, laser marking, cleanroom assembly, laboratory verification and final packaging — all inside the same plant. That means fewer handoffs, faster sample rounds and a production schedule our customers can plan around.
- Injection devices, glass ink cartridges and injection pen cases
- Mold making and medical-grade molding in house
- Cleanroom assembly and released-batch documentation
Core manufacturing
Six stages of production we run ourselves
01
Precision mold & tooling
In-house mold design and tooling for stable part geometry, fast sample loops and repeatable mass production.
02
Medical-grade injection molding
Automated molding cells with process parameters recorded per batch for medical device components.
03
Laser marking & traceability
Laser etching of batch, scale and private-label markings with traceable records for each production run.
04
Cleanroom assembly
Assembly and visual inspection carried out in a Class 100,000 cleanroom by trained line operators.
05
Laboratory verification
Dimensional, leak and force checks recorded against each released batch before release.
06
Final packaging
Cleanroom packing, labelling and carton release prepared for export shipments.
Step 02
Core manufacturing processes
Molding cells run medical-grade resins with recorded parameters. Parts move to laser marking, then into the cleanroom for assembly and visual inspection before packaging and export preparation.
- Precision mold design, tooling and maintenance
- Automated injection molding with recorded parameters
- Laser marking for scale, batch and private label
- Class 100,000 cleanroom assembly and packing
Step 03
Quality control and laboratory verification
Every device is inspected before it leaves the line, and each released batch is accompanied by inspection records so our customers can file them with their own quality documentation.
- Incoming material and in-process inspection
- Physical laboratory for functional and durability testing
- Per-unit inspection before packaging
- Released-batch inspection records
Step 04
Certifications and compliance
Certification details and scope statements are provided by the manufacturer on request. Registration outcomes always depend on the final product configuration, intended use and the importing market, so we present capabilities here rather than guarantees.
- ISO 13485 based quality management system
- CE technical documentation support
- FDA registration pathway support
- Documents issued against official certificates and contracts
