Aluminum Alloy Drive Arm Crank, through the review to the geometry and the required dimensions and tolerances from the print, we will all find this part is simple, the part is used as driven arm crank on the windscreen wiper, the carried Die Casting criterion for this part is Grade GB-CT4, in application, the part will rotate with the driven structure of the wiper, so the only key characteristic is to pay attention to the mechanical property as the part have to pass at least tens of thousands of rotation under required load.
The part is offered to us for a competitive price, after our trial production for the samples and submit a few pieces of samples, the customer will test with their specially designed facility, which can simulate the rotation in actual application on the car or the boat.
Our factory has specialized in high pressure die casting industry for more than 16 years, we have rich experience in the die casting work, usually we can provide a lot of recommendations based on the geometry of the current design during phase of development. such as enlarge the radius at the corner or edge to prolong the tooling life, to hollow the part by only adding strengthen ribs, not only to save the material cost for the customer, but also to make the part more suitable for die casting work, what's more, the part has functional requirement on the mechanical property, with radius to the corner of the part, will make the part stronger, not easy to be broken, the corresponding R angle on the mold also will be very helpful for tooling life as it can relief the problem of stress accumulation.
At last, the part require surface finish of electrophoresis coating, in order to make the part have much better effect, prior to this surface finish, we will add the tumbling process as the pre-treatment. this work can improve the appearance situation, such as make the area after deburring with pneumatic file, which may have some small issue like scratch, deburring mark etc.
