Sand Casting Aluminium Smart Door Latch

Sand Casting Parts is an intelligent door lock buckle made of die cast aluminum as the base material.The general construction is a long asymmetrical strip with a circular fastening with a left cut, can be strongly arranged using the cylindrical construction of the closure body in connection with the surrounding fastening holes; The middle part is a supporting hand with support points, which can stably transmit the unlocking and locking actions; On the right is the installation platform with cavity weight reduction construction.

Step 1: In the machining process, we first obtain die cast aluminum blanks through Customized Sand Casting Service, ensuring that complex contours are formed in one go and reducing subsequent machining allowances.

Step 2: Transfer the raw material for the precision milling to the CNC machining center. First, the casting is effectively removed by the rough milling machine, then high-precision cutting is carried out on the mounting surface, the key positions of the holes and the outer contour are realized using high-speed precision milling machines. The equality and position tolerances of the holes are strictly controlled at ± 0.01 mm to ensure precise adaptation of each mounting interface.

Step 3: After milling, unplug the sharp edges. After the end of the mechanical treatment, the detail passes to the surface treatment step: first, it is subjected to chemical degreasing and acid washing to remove the treatment residues, then it is subjected to a natural anodized treatment to obtain on the surface a layer of aluminum oxide with a thickness of 8-12 μm.

As a professional manufacturer of CNC processing services, Dongguan Shengpeng Precision Technology Co., Ltd. We offer simultaneous services from Sand Casting Plant to precision CNC processing. We support a comprehensive adaptation, whether it is dimensional adjustment, material exchange or modification of the surface treatment process, everything can be made on request to meet your individual needs in different industrial scenarios.
