Tube demolding after tip forming machine production

Catheter demolding after tipformer production is a critical step that must be performed carefully to ensure the quality of the molded product. The following are some of the factors and recommendations to be considered during the demolding process:

Timing of demolding
– Adequate Cooling : Ensure that the conduit has cooled and cured sufficiently in the mold to minimize deformation caused by plastic that has not fully hardened during demolding.
– Cycle time: Optimize cycle time to ensure productivity and avoid product quality problems caused by premature demolding.

Control of demolding force
– Force Control: Control the release force applied to the conduit to avoid excessive force that could cause damage to the product.
– Uniform force application: Ensure that the release force is evenly distributed on the product to avoid localized stress concentration.

Design of release angle and path
– Mold Design : The mold design should consider the release path and angle to minimize the impact on the molded product.
– Smooth guiding system : Ensure that the guiding system, such as pusher, slider, etc., is properly designed and smooth.

Inspection after demolding
– Integrity check : Immediately after demolding, check the integrity and dimensional accuracy of the product to ensure that there is no damage or deformation.
– Quality Control: Strict quality control procedures are performed to ensure consistent product quality during the demolding process.


A proper demolding process is critical to ensure the quality of the tip-forming catheter. Careful mold design, selection of appropriate process parameters, and continuous monitoring and maintenance of equipment are required to maintain optimal production conditions. If there are problems with the demolding process, it may be necessary to go back to the mold design and process optimization stages to make the necessary adjustments.
