Two-Shot Overmolded Plastic Lid Mold for Tissue Boxes
1. Introduction
Two-shot overmolded plastic lid molds for tissue boxes are designed to produce durable, aesthetically appealing, and functional lids that offer a combination of soft-touch and rigid plastic materials. This process integrates hard plastic (such as ABS or PP) with a soft rubber-like material (TPE/TPU), enhancing usability, comfort, and sealing performance.
This molding technology is widely used in household, office, and automotive tissue dispensers, where a combination of strength, flexibility, and visual appeal is required.
2. Characteristics of Two-Shot Overmolded Tissue Box Plastic Lid Molds
- Dual-Material Design for Functionality & Aesthetics:
- Combines a rigid base for structural support with a soft-edge opening for smooth tissue dispensing.
- Seamless Overmolding for Durability:
- Strong adhesion between two materials ensures longevity and prevents peeling.
- Smooth & Comfortable Touch:
- Soft rubber edges offer a pleasant feel and easy tissue pulling experience.
- Enhanced Sealing & Anti-Dust Features:
- Flexible material helps prevent dust accumulation and maintain hygiene.
- Customizable Designs:
- Available in various shapes, colors, and textures to match home décor or brand preferences.
- Optimized for Mass Production:
- Multi-cavity mold design ensures high efficiency and cost-effectiveness.
3. Manufacturing Process of Two-Shot Overmolded Tissue Box Plastic Lid Molds
1. Mold Design
- 3D CAD Modeling (SolidWorks, UG, CATIA) for precise shaping and fit.
- Mold Flow Analysis (Moldflow, Autodesk Simulation) to ensure smooth material bonding.
- Rotational or Core-Shift Mold Mechanism:
- Ensures precise positioning for the second-shot overmolding.
2. Mold Fabrication
- High-Precision CNC Machining:
- Ensures tight tolerances for seamless part assembly.
- EDM (Electrical Discharge Machining):
- Used for intricate detailing and smooth finishes.
- Texturing & Surface Treatment:
- Glossy or matte textures for improved aesthetics and touch feel.
3. Two-Shot Overmolding Process
- First Injection (Rigid Base - ABS/PP/PC):
- The core structure of the lid is molded.
- Mold Rotation or Core Shift:
- The first molded part remains in place while the mold adjusts for the second shot.
- Second Injection (Soft Overmolding - TPE/TPU):
- A flexible material is overmolded onto the dispensing area or edges.
- Cooling & Ejection:
- Optimized cooling channels enhance production speed and quality.
4. Quality Control & Inspection
- Material Bonding Strength Test: Ensures strong adhesion between hard and soft materials.
- Dimensional Accuracy Inspection: Verifies fitment with the tissue box structure.
- Surface Finish Analysis: Checks for scratches, bubbles, and flow marks.
- Soft-Touch Durability Test: Ensures long-lasting comfort and usability.
4. Applications of Two-Shot Overmolded Tissue Box Plastic Lids
- Household Tissue Dispensers: Elegant, ergonomic lids for home use.
- Office & Commercial Tissue Boxes: Durable lids for professional settings.
- Car Tissue Holders: Compact, soft-edged lids for easy dispensing in vehicles.
- Luxury & Custom Branded Tissue Cases: Premium designs for hotels and restaurants.
5. Conclusion
Two-shot overmolded plastic lid molds for tissue boxes enhance functionality, comfort, and aesthetics, providing a durable and user-friendly solution. The integration of rigid plastic and soft rubber materials through advanced molding techniques ensures high-quality, cost-effective, and scalable production for various consumer and commercial applications.Contact NeedMold,Email us: manager@needmold.com
