Plastic crib parts moulding

In addition, our company has established cooperative relationships with plastic raw material suppliers, printing manufacturers, etc. to ensure the supply of raw materials and printing quality. Through our rich experience and perfect supply chain, our company can provide customers with high-quality customized plastic crib parts moulding products to meet their specific needs. At the same time, we have 10 years of professional foreign trade service experience, understand the foreign trade process, and better serve our customers. For plastic crib parts moulding products, we can make corresponding plastic parts, which is mainly done through injection molds.

Crib parts are directly related to the safety of infants and toddlers, so their production process has extremely high requirements for safety, environmental protection and quality consistency. The entire process is based on the general injection molding process and has stricter control standards.

The following is the detailed forming process:

Phase One: Safety Compliance and Design

This is the foundation of all work and is more crucial than ordinary products.

Safety standard confirmation: Firstly, it is necessary to clearly define the safety standards for cribs in the target market (such as China GB, the United States ASTM F1169, the European Union EN 716, etc.). These standards have mandatory regulations on the mechanical and physical properties (strength, durability), flame retardancy, and the content of chemical substances (such as phthalates, heavy metals) of parts.

Material selection

Preferred material: It must be food-grade or medical-grade plastic, such as PP (polypropylene), HDPE (high-density polyethylene). These materials are non-toxic, odorless, chemically stable, impact-resistant and easy to clean.

Core requirements: Only brand new materials must be used. The use of recycled materials or waste of unknown origin is strictly prohibited. Raw material suppliers are required to provide relevant food safety certifications (such as FDA, LFGB) and material certificates.

Product and Mold Design

Safety structure: When designing, any sharp edges and points that may cause pinching or scratching should be avoided. All corners and edges should be rounded.

Structural strength: Ensure the strength of load-bearing components such as guardrails and bed plates through reasonable reinforcement rib design, and simulate the force conditions through CAE analysis.

Mold design: The design of the runner, cooling and exhaust systems of the mold should aim at minimizing defects to the greatest extent. The steel for molds must be of high quality to ensure the stability of long-term production and the smoothness of the parts' surfaces, and to prevent dirt and grime from accumulating.

Phase Two: Strict pre-production preparations

Raw material pretreatment

Strict drying of materials: Even new materials must be dried strictly in accordance with the material supplier's recommendations (for example, PP should be dried at 80-100℃ for 2-3 hours) to remove trace amounts of moisture and prevent the product from developing bubbles or silver streaks.

Specialized barrel: The equipment should be dedicated or thoroughly cleaned to prevent contamination by raw materials of different colors or types.

Equipment and Environmental preparation

Injection molding machine cleaning: Ensure that the injection molding machine's barrel and screw are extremely clean, free of any residual materials from previous production.

Cleanroom: The production environment is best to meet the standards of a dust-free workshop to prevent dust from settling on the product surface.

Phase Three: Core injection Molding process

This stage is similar to the general process, but the parameter control is more precise.

Feeding: Feed the dried pure raw materials into the hopper of the injection molding machine.

Plasticizing: Solid particles are transformed into a molten state through heating and screw shearing. Temperature control must be precise to prevent material degradation due to excessively high temperatures.

Injection and pressure holding: Molten plastic is injected into the mold cavity and subjected to sufficient pressure holding to prevent product shrinkage and ensure dimensional stability and structural compactness.

Cooling and mold opening: After cooling and setting in the mold, the mold is opened.

Automated pick-up: Use mechanical arms to pick up items to avoid product contamination or scratches caused by manual contact.

Phase Four: Post-processing and secondary processing

Gate removal: Remove the sprue material from the part. After removal, it must be ensured that there are no burrs or sharp edges. Usually, special fixtures or equipment are required for trimming.

Necessary assembly: If the crib is composed of multiple plastic parts, ultrasonic welding or mechanical snap-on assembly may be carried out. Welding must ensure strength and the welding area should be smooth without sharp corners.

Phase Five: Comprehensive Quality Inspection (Extremely important!)"

This is the core link to ensure the safety of the crib, usually involving online inspection and offline spot checks.

First piece inspection: After each shift starts up or changes the mold/material, conduct a comprehensive measurement and inspection of the products from the first few molds produced.

Online inspection: Quality inspectors regularly (such as every hour) take products from the production line for inspection.

Inspection content

Appearance inspection: Whether the surface is smooth, whether the color is uniform, and whether there are defects such as shrinkage, bubbles, scratches, stains, and burrs.

Dimensional inspection: Tools such as calipers and three-coordinate measuring machines are used. Critical dimensions must 100% conform to the tolerances of the drawings.

Functional inspection: Check whether the clips, sliding parts, etc. are assembled smoothly and function normally.

Special safety inspection

Sharp point and edge test: Use professional instruments (such as sharp point and edge testers) to inspect all accessible parts.

Small component test: Simulate a child pulling to ensure no small components fall off and prevent the risk of suffocation.

Strength testing: Regularly conduct load-bearing, impact and durability tests on the products (such as simulating children jumping and shaking guardrails multiple times).

Traceability: Each batch of products and even parts should have traceable labels (such as date codes, batch numbers), so that in case of problems, the raw materials, production machines and shifts can be quickly traced back.

Phase 6: Packaging and Warehousing

Cleaning: The parts may need to be cleaned before packaging to remove the dust adsorbed by static electricity.

Individual packaging: Each important part is usually individually packaged in a PE bag or bubble wrap to prevent scratches during transportation.

Marking and Warehousing: The product name, part number, production date, material and other information should be clearly marked on the packaging box. Qualified products should be wareited for shipment.
