Baito Mold: The Optimal Solution for High-Precision Plastic Injection Moulding

The detail information of product

VINACNC - Expert in High-Precision Customizable Collapsible Core Plastic Injection Molds

In the mold industry, producing plastic parts with internal threads or undercuts (features that cannot be ejected in a straight vertical direction) requires a special mould solution. VINACNC is proud to offer the manufacturing service for plastic injection molds with a customizable collapsible core design, also known as a Baito mold in some markets. This is the optimal solution for ensuring high accuracy and production efficiency for even the most complex plastic parts.

Technical Specifications, Materials, and Applications

Mould Material: The molds are crafted from high-quality tool steels such as SKD61, NAK80, 718, or other grades based on customer requirements. These materials are known for their high hardness and good wear resistance.
Collapsible Core Design:
- The collapsible core mechanism is specially designed to retract and detach from the undercuts or threads of the plastic part during the mold opening process.
- This design eliminates the need for complex side-actions or lifters, thereby shortening the molding cycle time, reducing maintenance costs, and extending the mould's lifespan.
Technical Properties:
- High Accuracy: The molds are machined to extremely tight tolerances, ensuring that the parts have precise dimensions, especially in the threaded and undercut areas.
- Product Quality: Ensures that the surface of the molded plastic part is free of marks or defects caused by the ejection process.
Applications: Collapsible core molds are widely used to produce plastic parts for:
- Automotive Components: Fuel tank caps, valves, and threaded parts.
- Medical Devices: Threaded bottle caps, syringe components.
- Household Appliances: Caps, containers with threads, and parts with snap-fit features.

Product and Service Advantages

Superior Accuracy: Thanks to the advanced collapsible core mechanism, the mold ensures the accuracy of threaded and undercut parts, resulting in a perfectly functioning final product.
Optimized Production Efficiency: The shorter molding cycle time and reduced product defects boost overall productivity and efficiency.
Durability and Longevity: With optimized materials and heat treatment processes, the mold can withstand repetitive pressure and friction, extending its lifespan.
Flexible Customization: We provide on-demand manufacturing services, from collapsible core design to mass production, ensuring the product perfectly matches the client's blueprints and intended use.

Post-Machining Product Inspection Process

Dimensional and Tolerance Check: We use a Coordinate Measuring Machine (CMM) and other high-precision measuring tools to verify the dimensions of the mold and the produced parts.
Surface Inspection: We conduct a visual inspection and use specialized measuring devices to ensure the mold surface meets requirements and is free of cracks or defects.
Mould Trial Run: A trial run on a real injection molding machine is performed to evaluate the quality of the sample parts, optimize molding parameters, and ensure stable mold operation.

Packaging and Storage Process

Cleaning and Rust Prevention: The mold is cleaned and coated with a specialized anti-rust oil to protect its precision surfaces.
Secure Packaging: The product is carefully packed in a sturdy wooden crate with foam or shock-absorbing materials to prevent damage during transport.
Labeling and Instructions: The packaging is clearly labeled with product information, including the product code, weight, dimensions, and handling instructions.
Storage: We recommend storing the mold in a dry, temperature-stable environment to prevent rust and damage.
