Waterjet Cutting, Gun Drilling, Special Machining, & Surface Contouring

Waterjet Cutting

Abrasive waterjet cutting from Mac Mold Base expands our capacity for mold base production and opens the door to a variety of service work from aerospace, jig and fixture, defense, advertising and more!
Custom Mold Bases

Our competitive advantage is that we specialize in the most difficult custom mold bases that can be manufactured for overmolding, rotational, shuttle, closure, stack, compression, thermoset, unscrewing, plastic injection...
Gun Drilling

Mac-Mold Base is best known for custom mold bases. However, we also offer contract gundrilling in standard and metric. Drilling capacity of up to 2” diameter, with maximum depth from one edge of 84”, and a total depth of 168”.
3D Machining

MMB will 3D machine and surface contour as a service to the mold and die cast industry. We use either a vertical or horizontal mill that can handle the largest molds. When a customer receives a completed base that has the cavity and core roughed and stress relieved, it gives a jump...

Services & Capabilities

MMB is able to handle a variety of outside work in addition to large and custom mold bases. We have strategically invested in machinery that is beneficial to our mold base production but is also capable of handling other machining tasks. It is this diversity that keeps us competitive. From our Tarus 4 Axis STS gundrill, Mitsubishi DX 612 abrasive CNC waterjet to our large capacity horizontal and vertical milling centers, we are ready and able to handle any project you may have.

Mac-Mold Base's quality control program is guided by the inspection department, which scrutinizes each phase of your job, monitoring and ensuring critical tolerances, proper assembly, clean-up, components, and crating.

Engineering Capabilities

Mac-Mold Base uses MasterCAM, AutoCAD, and Cadkey formats. If your file does not respond to one of these formats, please send them via IGES formats. All files transferred to Mac-Mold Base should correspond to your project number followed by a "P" for Preliminary, or an "F" for Final. In addition, for all larger files please use our FTP site listed below.

Our team consists of experienced engineers paired with a highly trained and motivated group of CNC Machine operators, backed up by our inspection department that is precise and trained to assemble quality mold bases.

We can execute...

We can execute the most challenging tolerances, up to .0002":

Sizes of plates and/or mold bases: Up to 60" x 150" (1524mm x 3810mm)
Weights: Mac Mold can handle up to 10-ton capacity. With special arrangements, we are capable of processing up to 30 ton capacity.
Some of the components we machine for are: ejector pins, slides, sprue puller pins and bushings, core pins, ejector sleeves, step pins, springs and slider locks.
Most work is done in-house, and we have excellent vendor supply of plate steel and alloys to insure on-budget and on-time shipping of your job. We do CNC milling, plate grinding and gundrilling. (See our gundrilling page for our New Tarus 4 axis CNC Deep Hole Gundrill)
Each mold base is completely assembled and fully inspected before shipping, insuring a fast, simple and problem free mold base.
