Gas-assisted injection molding process has high requirements on raw materials, which require good flow and thermal stability of raw materials.
Gas-assisted injection molding is a kind of injection molding process in which plastic melt is filled in the mold by air flow. The process improves plastic fluidity and fillability by injecting compressed air into the molten plastic to form bubbles for better mold filling.
Why Gas-Assisted Injection Molding is Chosen
1. Requirement for Thick-Walled Structures
The handle at the top of the casing is a typical thick-walled structure. If conventional injection molding were used, issues like sink marks, warpage, or internal stress would likely occur in the thick sections. Gas-assisted injection molding resolves these problems perfectly by injecting high-pressure nitrogen to form a hollow structure, ensuring a smooth and defect-free surface.
2. Long and Thin Integrated Structure
The entire casing features a long and thin shape. Gas-assisted molding can create internal support channels, enhancing overall rigidity while reducing weight. This is crucial for medical equipment that requires frequent handling.
3. Medical-Grade Surface Requirements
Gas-assisted molding produces a smoother surface with lower internal stress, meeting the strict requirements for easy cleaning and resistance to sterilization in medical devices.
Detailed Process Steps
1. Step 1: Short Shot Injection
Approximately 70%–80% of medical-grade ABS/PC plastic melt is injected into the mold, filling most of the cavity but leaving the thick-walled areas and the handle section unfilled.
2. Step 2: Gas Injection
Immediately after, high-pressure nitrogen is injected through gas pins in the mold. The gas penetrates the melt, pushing the plastic to fill the entire cavity while forming a hollow structure in thick sections like the handle.
3. Step 3: Gas Pressure Holding
The gas pressure is maintained until the plastic cools and solidifies, ensuring the surface adheres closely to the mold and preventing shrinkage or sink marks.
4. Step 4: Exhaust and Mold Opening
The nitrogen is vented, and the mold is opened to remove the formed casing. Finally, logo printing and surface cleaning are performed.
Key Features
Medical-Grade Injection Molding
The entire enclosure is molded in a single high-pressure process using biocompatible, disinfectant-resistant ABS/PC plastic. This ensures uniform wall thickness, tight dimensional tolerances, and a seamless, easy-to-clean surface that withstands repeated exposure to alcohol and hospital-grade cleaners.
Ergonomic & Functional Design
The integrated side handle enables secure, one-handed transport by healthcare staff, while precision-cut openings for sensors, scanners, and ventilation grilles are molded directly into the housing, eliminating post-production modifications and ensuring a perfect fit for internal components.
Robust Structural Integrity
Reinforced ribs and precision-molded snap-fit joints provide exceptional rigidity, protecting sensitive electronics from drops and impacts. The enclosure meets IP30 dust and splash protection standards, safeguarding internal circuits in busy clinical settings.
Branded, Professional Finish
The high-gloss, scratch-resistant surface is printed with the CAPSA Healthcare logo, delivering a clean, professional appearance that aligns with the stringent hygiene standards of hospitals and clinics.
Tool-Free Assembly
Precision-molded alignment pins and integrated snap locks enable quick, tool-free assembly, reducing production time and ensuring consistent quality across every unit.
