Job Responsibilities
Die & Tooling Design
- Design profile extrusion dies, including flow channels, land lengths, and die plates, for rigid PVC fence posts, rails, pickets, caps, and accessory profiles.
- Design calibrators/sizers, vacuum tanks, cooling fixtures, puller pads, and cutter/punch tooling to match profile geometry and line speed.
- Design co-extrusion and capstock feed systems to achieve uniform cap layer thickness and weatherable surfaces.
- Apply flow balancing, drawdown, swell, and shrinkage allowances to hit nominal dimensions and wall thickness with minimal tuning.
New Product & Profile Development
- Translate product drawings and customer requirements into complete die and calibration tooling packages.
- Review new profile designs for manufacturability and recommend geometry changes to improve extrudability, rate, and cost.
- Lead tooling trials and commissioning of new dies with Die Tuners and Production, documenting results and design iterations.
Tooling Performance & Continuous Improvement
- Die Tunning
- Analyze tooling-related defects (dimensional drift, warp, bow, die lines, gloss variation, wall thickness variation) and implement design corrections.
- Drive improvements in line speed, scrap rate, changeover time, and tooling life through design upgrades and standardization.
- Evaluate die steels, coatings, and surface treatments to improve durability and surface finish.
Supplier & Toolroom Management
- Manage external die shops and toolmakers: prepare RFQs, review quotes, approve designs, track lead times, and inspect incoming tooling.
- Provide machining guidance to the in-house toolroom for modifications, rework, and repairs (CNC, EDM, polishing).
Documentation & Standards
- Maintain 3D models, 2D drawings, bills of material, and revision control for all dies and tooling.
- Develop tooling standards, design guidelines, and setup sheets in partnership with Die Tuners and Process Engineering.
- Support quality and compliance requirements, including ASTM F964 and customer specifications for PVC fence profiles.
Safety & Collaboration
- Ensure tooling designs incorporate safe handling, lifting, and changeover practices.
- Partner with Manufacturing, Maintenance, Quality, and Product Development teams to ensure tooling supports business goals.
- Perform other related duties as assigned.
Job Requirements
- Bachelor's degree in Mechanical, Plastics, or Manufacturing Engineering, or equivalent combination of education and hands-on experience.
- 5 plus years of experience designing profile extrusion dies and tooling, preferably for rigid PVC (vinyl) fence, railing, siding, decking, or window profiles.
- Proficiency in 3D CAD (SolidWorks or equivalent) and 2D drafting, including GD&T.
- Strong understanding of polymer flow, rheology, die balancing, and calibration/cooling principles; experience with die flow simulation software is a plus.
- Working knowledge of machining processes used in toolmaking (CNC milling, wire/sinker EDM, grinding, polishing).
- Experience with co-extrusion and capstock systems preferred.
- Strong analytical, problem-solving, and communication skills; able to work hands-on at the extrusion line.
- Ability to travel up to 35% to suppliers and sister facilities.
What CRH Offers You
