Positioner Cold Pressing Needle Process Flow

The positioner crimp contact process is a technology that combines metal parts with plastic or rubber materials through mechanical pressure. crimp contact pin It is mainly used for precision assembly of electronic components, automotive parts, etc. contact socket crimp The process is divided into three stages: preparation, operation, and inspection. The parameters and specifications must be strictly followed to ensure crimp contact female accuracy and durability. The following are specific steps and key points:
crimp contact male Material and equipment preparation
crimp socket contact The materials include the positioner metal matrix, plastic/rubber filler, and special lubricant. female crimp contact The metal matrix needs to be cleaned of surface oil and oxide layer in advance, and treated with an ultrasonic cleaner for 5-10 minutes to ensure that there are no residual impurities. The filler is mixed in proportion. If it is a thermoplastic material, it needs to be preheated to 80℃±5℃ to maintain fluidity. The equipment includes male crimp contact machines, positioning molds, and pressure sensors. The molds need to be customized according to the product drawings, and the tolerance is controlled within ±0.02mm. Before starting the machine, check the oil level and circuit stability of the hydraulic system, run it three times without load, and confirm that the pressure gauge reading is consistent with the set value.
