Aluminium Filter Housing Mold

In this project, developed for irrigation and filtration systems, we designed and built the injection mold for an aluminium filter head that operates under pressure. The key requirements were that the part be porosity-free for sealing and that the threaded and gasket areas could be machined afterwards.

In the mold design, we laid out the gating and venting system to reduce the risk of porosity, and together with the customer we determined the areas where machining allowances would be left.

• CAD-CAM 3D mold design
• Gating, overflow and venting system that reduces the risk of porosity
• Mold steel resistant to thermal load and cooling channel layout
• Machining allowance planning for threaded and gasket areas

The mold cavities and cores were machined on CNC vertical machining centers. The clamping references for the threaded and gasket surfaces to be machined after casting were defined at the mold design stage, which also made the part's subsequent machining repeatable.

In the trial castings, filling, porosity and dimensional checks were carried out; the threaded and gasket areas were verified on machined samples. [PLACEHOLDER] Add pressure test and correction details.

The mold was delivered for series production; the filter head is produced as parts that meet the sealing requirement, with well-balanced machining allowances. [PLACEHOLDER] Add results such as production quantity and scrap rate.
