– Conduct feasibility analysis
– Decision-making before the next stage

Engineering phase
– Completion of detailed component design
– Machining decisions
– Material decisions
– Sample testing
– Evaluation and redesign

Manufacturing phase
– Mold design, fabrication and evaluation
– Mold cavity filling analysis
– Selection of manufacturing equipment
– Component testing
– Customer evaluation
The machining of a tip forming mold is a delicate process that involves multiple steps and technical points. To ensure the quality and accuracy of your mold, the following is a basic guide to machining a tip forming mold:

Design Phase

1. Mold design :
– CAD/CAM software: Use advanced computer-aided design and manufacturing software to design the mold.
– Mold flow analysis: Perform mold flow analysis to optimize the design of gates, runners and cooling systems.
– Material selection : Selection of suitable mold materials, taking into account hardness, wear resistance and heat treatment properties.

Material Preparation

2. Material Selection :
– Select suitable steel or other alloy materials according to the mold design and expected production volume.
– Consider the machinability, hardness, corrosion resistance and thermal conductivity of the material.

Processing Stage

3. Rough machining :
– Milling : Rough milling using a large CNC milling machine to remove excess material.
– Drilling : Drill out the cooling channels and other necessary holes.

4. Finishing :
– CNC machining : Fine machining using high-precision CNC machines to form the exact shape of the mold.
– EDM (Electro Discharge Machining) : Used to process complex shapes or hard materials that are difficult to process by conventional methods.
– Wire Cutting : Wire cutting technology is used for parts that require high-precision linear cutting.

5. Surface treatment:
– Polishing : The surface of the mold is polished to reduce friction when the product is removed from the mold.
– Heat treatment : Appropriate heat treatment is applied to increase hardness and wear resistance.
– Coating : Apply coatings such as chrome plating to increase corrosion resistance and hardness.

Assembly and Testing

7. Commissioning :
– Install the mold on the tip forming machine and conduct a trial molding.
– Adjust the mold according to the result of the trial molding to ensure the quality of the finished product.


8. catheter tipping dies Maintenance :
– Regularly check the wear and tear of the molds and carry out the necessary care and maintenance.
– Keep the mold clean and clean the cooling channels and release agent residue regularly.

Quality Control

9. Quality Inspection :
– Perform dimensional and functional inspections of completed molds.
– Use precision measuring tools to ensure that the mold is accurate as designed.

By following the above guidelines, you can ensure the quality of the processing of the tip forming molds, thus improving productivity and the quality of the finished product. It should be noted that mold processing is a process of continuous learning and improvement, and continuous technology upgrading and experience accumulation are crucial to enhance the level of mold processing.
