Comprehensive specifications for mold appearance, markings, accessories, spare parts, and documentation in plastic mold injection manufacturing
In the field of plastic mold injection, maintaining consistent standards for mold construction and documentation is crucial for ensuring product quality, operational safety, and manufacturing efficiency. Properly designed and maintained plastic mold injection systems reduce downtime, improve production consistency, and extend mold lifespan. This document outlines the industry's most成熟 (mature) and comprehensive standards for plastic mold injection components, covering appearance requirements, safety markings, essential accessories, critical spare parts, and necessary documentation.
Adhering to these plastic mold injection specifications ensures that all stakeholders - from design engineers to production operators - have a clear understanding of mold requirements and maintenance procedures. These standards have been developed through years of industry experience and represent the optimal practices for plastic mold injection manufacturing.
Mold Appearance and Identification
1. Surface Treatment
All external surfaces of the plastic mold injection, except for the contact surfaces between templates, must be coated with anti-rust treatment. This protective layer is essential for preserving the integrity of the plastic mold injection during storage and between production runs.
The specific colors used for different classifications of plastic mold injection must comply with internal factory regulations. This color-coding system helps in quick identification of mold types, applications, and maintenance requirements in a busy plastic mold injection facility.
2. Safety Warning Markings
All plastic mold injection units must display appropriate warning markings on relevant components to ensure safe operation. These markings are critical for preventing accidents and ensuring proper handling of the plastic mold injection during setup, operation, and maintenance.
Examples of necessary warnings include "Plastic mold injection has pre-reset requirements" and "Ejection stroke XXmm". These markings must be clearly visible, durable, and resistant to the harsh environment of plastic mold injection facilities, including exposure to oils, cleaning agents, and high temperatures.
3. Identification Nameplate
Each complete plastic mold injection must be equipped with a permanent nameplate securely attached to a visible, accessible location. This nameplate serves as the official identification for the plastic mold injection throughout its lifecycle.
The nameplate for plastic mold injection should include essential information such as mold number, part number, date of manufacture, material specifications, weight, maximum operating parameters, and manufacturer information. The nameplate must be constructed from durable materials capable of withstanding the industrial environment of plastic mold injection facilities.
Additional Appearance Requirements for Plastic Mold Injection:
- All visible surfaces of the plastic mold injection must be free from excessive burrs, scratches, or other imperfections that could affect safety or performance.
- Welded areas on the plastic mold injection must be ground smooth and properly finished to prevent injury during handling.
- All fasteners used in the plastic mold injection must be of appropriate grade and properly tightened, with exposed heads finished to match surrounding surfaces where possible.
- Edges of the plastic mold injection that could pose a safety hazard must be rounded or covered with protective guards.
- Any modifications to the plastic mold injection must be clearly marked and documented, with updated information reflected on the nameplate when necessary.
Mold Accessories
Proper accessories are essential for the safe and efficient operation of any plastic mold injection system. These components facilitate handling, positioning, connection to auxiliary systems, and overall functionality of the plastic mold injection during the manufacturing process.

2. Lifting Ring Specifications
Proper lifting equipment is critical for the safe handling of plastic mold injection, which can be extremely heavy and awkward to maneuver.
- For plastic mold injection with lifting hole sizes of M20 or smaller, lifting rings must be permanently installed.
- For plastic mold injection with lifting hole sizes of M42 or larger, lifting rings must be included as standard equipment.
- For plastic mold injection with lifting hole sizes between M20 and M42, if lifting rings are required, this must be specifically noted in the plastic mold injection documentation.
- All lifting rings for plastic mold injection must be rated for at least 125% of the mold's total weight to provide an adequate safety margin.
- Lifting points on the plastic mold injection must be symmetrically positioned to ensure balanced lifting and prevent tipping.
3. Supporting Mold Feet Requirements
Supporting feet provide stability for plastic mold injection during storage, transportation, and when not installed in the injection molding machine.
- Supporting feet for plastic mold injection are not required if the mold's outer structure does not interfere with placement or transportation when the mold is set down.
- When required, supporting feet on plastic mold injection must be of sufficient height to prevent damage to protruding components such as nozzles or hydraulic connectors.
- Supporting feet must be securely fastened to the plastic mold injection and capable of supporting the entire weight of the mold without deformation.
- Feet on plastic mold injection should be equipped with non-slip surfaces or pads to prevent movement during storage.
- All supporting feet must be adjustable to accommodate uneven surfaces when necessary for proper plastic mold injection storage.
