Products Description
Standard Processing Steps for Electric Kettle Mold Base

  1. Blanking
    Use a sawing machine to cut standard steel plates into rough blanks of the required size.

  2. Rough Milling (Face Milling and Side Milling)
    On a gantry milling machine, mill the six faces of the plate (primarily the reference large faces) flat and machine the basic external dimensions, removing most of the machining allowance.

  3. Drilling Lifting Holes/Process Holes
    Drill screw holes (lifting holes) and reference pin holes on a drilling machine for hoisting, handling, and positioning in subsequent processes.

  4. Rough Cavity Milling (Roughing)
    Use a rough cavity milling machine or gantry milling machine to preliminarily machine the mold cavity, guide pillar/bush holes, return pin holes, and other structural features on the mold base, leaving a uniform finishing allowance for all areas to be machined.

  5. Heat Treatment (Quenching and Tempering)
    [Key Process] Perform quenching and high-temperature tempering on the roughly machined plate. The purpose is to relieve internal stresses generated during rough machining, uniformly improve the comprehensive mechanical properties (strength, toughness) of the steel, and provide a stable material condition for subsequent finishing.

  6. Precision Grinding of Reference Surfaces
    After heat treatment, the plate may undergo slight deformation. This process is performed on a precision grinding machine to grind the two most critical reference surfaces (typically A and B faces) to achieve extremely high flatness, surface finish, and precise thickness, providing a unique and accurate positioning reference for all subsequent finishing operations.

  7. Precision Milling
    Using the ground reference surfaces for positioning, perform precision machining on the four sides of the mold cavity, parting surfaces, shut-off surfaces, slider grooves, etc., on a gantry milling machine or precision milling machine to ensure perpendicularity, parallelism, and dimensional accuracy meet drawing requirements.

  8. CNC Machining
    For complex shapes that cannot be completed by precision milling (such as irregular curved surfaces, deep cavities, 3D runner systems, angled lifter holes, etc.), perform precision milling on a machining center (CNC) based on computer programming.

  9. Drilling and Tapping
    Drill all screw holes, ejector pin holes, water channel holes, guide pillar holes, etc., and perform tapping. This process is typically completed on a high-precision radial drill or CNC drilling machine.

  10. Benchwork
    Perform manual finishing, including chamfering all edges and corners, deburring, marking part numbers in specified locations, assembling standard components such as guide bushes and pins, and conducting water flow tests for cooling channels.

  11. Final Inspection
    Use inspection tools such as CMMs (Coordinate Measuring Machines), height gauges, and calipers to fully inspect all critical dimensions, hole position accuracy, and flatness, ensuring compliance with the design drawings.

  12. Assembly and Packaging
    Clean all components, including the front and rear mold bases, guide pillars, return pins, and ejector plates, then assemble them. Apply anti-rust oil, tighten fasteners, and package for shipment.

About Mold Bases
A mold base, also known as a mold frame, serves as the "skeleton" of a mold. It supports and secures all core components such as the mold core, sliders, and ejector pins. Its precision and stability directly determine the performance of the entire mold set.
