Heat Shrink Boots

Heat Shrink Boots

Heat Shrink Boots also referred to as Heat Shrinkable Boots, Wire Harness Boots, Heat Shrink Molded Shapes, Heat Shrink Tubing, Heat Shrink Cable Boots, which are used in a wide range of industries such as military, aerospace, automotive, and industrial. Often used in conjunction with heat shrink tubing, moldedshapes make it easy to fabricate wire and cable harnesses, offering strain relief, cosmetic coverings as well as environmentally sealed connections. Heat Shrink Boots/ Heat Shrink Molded Shapes are produced by compression mold and transfer injection mold.

Heat Shrink Boots Production Process by Transfer Molding

• Make mold tools - prepare steel material, complete the product & mold design.

• Prepare raw materials - Selected the type of material you want to use and calculate the proper amount of material. If too much material, excess material will seep out of the cavity and result in big flash which would be difficult to remove.

• Set up the machine parameters - after the mold is well-done, can get ready for the sampling to ensure the part dimension and surface is what we required, need to set up the machine parameters and heat up the mold.

• Place a piece of uncured rubber into a portion of the mold.

• The mold is closed up and under hydraulic pressure, the rubber is forced through a small hole into the cavity. The mold is held closed while the rubber cures.

• The plunger is raised up and the transfer pad material is removed.

• Mold is opened and the part can be removed. Any flash is trimmed and removed during this time. (Trimming flash, a secondary process that removes unwanted extra overflow material called flash)

 

Heat Shrink Boots Production Challenges

• Challenge 1: Short-shot;

  Solution: Inlarge the injection gate or increase the number of injection gate.

• Chanllenge 2: Demold-failed at 70A;

  Solution: Reduce the shore A/ durometer to 50A, the higher shore A it is, the more difficult to demold, generally for such design structure, the recommended shore A is 30A.

Rubber Transfer Molded Heat Shrink Boots Advantages

• Shorter production cycle times compared to traditional compression molding.

• Tighter dimensional tolerance.

• Closed mold transfer supports molding of complex geometries and over-molding.

• Flash and parting line are both small.

Rubber Transfer Molded Heat Shrink Boots Disadvantages

• "Pot" will increase gross material weight, which will waste more raw material.

• Higher tooling cost compared to traditional compression tools.

Heat Shrink Molded Shapes

• Heat Shrink Boots, T Transition

• 2 Way Heat Shrinkable Boots

• 3 Way Heat Shrink Boots

• 4 Way Heat Shrink Tube

• 5 Way Heat Shrink Molded Boots

• Right Angle Shrink Boots

• T Shape Wire Harness Boots
