CNC Machining
CrownMark CNC provides precision 3-axis computer numerical control (CNC) vertical milling for prototype components, tooling blocks, and production batches. Utilizing rigid machine setups and high-grade carbide cutting tools with dedicated flood coolant, we machine intricate geometries out of solid billet aluminum, brass alloys, copper, mild steel, and pre-hardened tool steels.
Our programming emphasizes smooth surface finishes, controlled chip evacuation, and tight dimensional consistency across individual parts and repeatable batches.
Typical Applications:
Billet Aluminum Brackets Custom Precision Hardware Tooling Plates & Fixtures Prototype Mechanisms
Laser Engraving & Marking
Our industrial fiber laser marking setup delivers high-contrast, permanent vector engravings on both bare and coated metals. From razor-sharp brand typography and micro-scale alphanumeric serial codes to deep metallic relief engraving, laser marking offers unmatched edge definition without mechanical stress on delicate workpieces.
We routinely mark anodized aluminum, stainless steel, polished brass, titanium, and chrome-plated zinc alloys for export apparel, surgical instrument blanks, and industrial machinery tags.
Typical Applications:
Metal Brand Labels & Plates Serial Numbers & QR Codes Embossing Die Surface Texture Custom Medallions
Custom Stamping Dies
CrownMark CNC manufactures custom hardened steel male/female stamping dies, punching punches, and blanking tools used to stamp metal tags, badges, belt hardware, and structural clips. We machine dies with precise shear clearances to prevent burring and ensure crisp, distortion-free stamped sheet metal parts.
Tool steel grades are selected and processed to withstand repeated industrial impact cycles while maintaining crisp dimensional edge profiles.
Typical Applications:
Embossing Punches Metal Tag Blanking Dies Leather Debossing Stamps Progressive Stamping Inserts
Rubber Logo Dies & PVC Molds
As a recognized specialty in the Sialkot sportswear and tactical manufacturing corridor, we machine solid brass and aircraft aluminum master dies for rubber logo emblems, silicone heat transfers, and soft PVC patches. Using micro-endmills with diameters down to fractions of a millimeter, we engrave multi-depth 3D logos, bevel relief angles, and textured backgrounds.
The brass thermal conductivity ensures rapid, uniform curing during vulcanizing or micro-injection, yielding sharp, high-definition rubber crests.
Typical Applications:
Sportswear Silicone Badges Tactical PVC Patch Dies Shoe Rubber Crest Molds Automotive Key Fob Dies
Gravity Casting Molds
We design and machine heavy-duty permanent gravity casting molds made from cast iron and specialized alloy steel blocks. These split molds feature precision-engineered runner systems, sprues, gates, and riser cavities designed for smooth laminar molten metal flow, minimizing air entrapment and porosity.
Widely used for manufacturing zinc alloy and aluminum hardware, zipper slider bodies, buckles, and decorative hardware.
Typical Applications:
Zinc Zipper Slider Molds Belt Buckle Casting Dies Aluminum Hardware Casings Decorative Metal Emblems
Precision Mold Manufacturing
CrownMark CNC manufactures multi-cavity precision tooling blocks, core and cavity inserts, and ejector mechanisms for plastic injection and composite compression molding. Utilizing rigid machine geometries, each cavity is milled with precise draft angles and parting lines to guarantee smooth ejection and zero flash.
We work with pre-hardened P20, H13, and stainless mold steels, providing polishing and surface texturing tailored to the molded resin requirements.
Typical Applications:
Multi-Cavity Slider Tooling Plastic Button & Toggle Molds Cord Lock Injection Tooling Industrial Enclosure Inserts
Custom Metal Component Manufacturing
From single custom prototypes to continuous production batches, we machine tailored metallic components for machinery, sports equipment, custom vehicles, and industrial assemblies. We machine tight-tolerance cylindrical shafts, threaded fittings, mounting flanges, spacers, and custom bushings.
Materials machined include 6061/7075 aluminum, free-cutting brass, 304/316 stainless steel, and engineering plastics like Delrin/POM.
Typical Applications:
Precision Bushings & Spacers Machinery Shafts & Pins Specialty Fasteners & Adapters Custom Brackets & Linkages
Copper Electrode Manufacturing (EDM)
Electrical Discharge Machining (EDM spark erosion) is essential for producing sharp internal corners, deep slots, and complex mold cavities that rotary cutting tools cannot physically reach. CrownMark CNC specializes in high-speed micro-milling of pure electrolytic copper electrodes with ultra-thin finned rib geometries and complex 3D profiles.
We compensate for spark gaps (orbital overcut allowances) directly in the CAM toolpaths, ensuring that spark-eroded mold cavities match design tolerances with extreme precision.
Typical Applications:
EDM Spark Erosion Tooling Deep-Rib Mold Electrodes Intricate Text & Logo Electrodes Electrolytic Tough Pitch Copper
