Jose Jr C.

Senior Mechanical, Mold Design & Manufacturing Engineer 31+ Years of Expertise in Injection Molding, Product Development, Rapid Prototyping, and Tooling Remediation Senior Mechanical and Mold Design Engineer with over three decades of comprehensive experience in injection mold design, plastic product development, and manufacturing leadership. Proven track record of transforming complex concepts into high-precision, production-ready tooling, supported by rapid prototyping and deep, hands-on expertise in machine setup, process troubleshooting, and mold repair supervision. Adept at bridging the gap between design and the shop floor, leveraging advanced skills in 3D CAD modeling, CNC programming, and Design for Manufacturability (DFM). As a former Mold Shop Head, I bring a rare, end-to-end perspective to engineering—ensuring that every design is theoretically sound, aesthetically validated, and highly efficient to run and maintain in real-world production. Core Competencies & Expertise • Injection Mold Design & Engineering • Plastic Product Development & DFM • Reverse Engineering & Design Remediation • Rapid Prototyping & 3D Printing (Additive Manufacturing) • Injection Molding Machine Setup & Troubleshooting • Process Parameter Optimization & Defect Resolution • Mold Maintenance, Repair Supervision & Refurbishment • 3D CAD Modeling & 2D Technical Drafting • CNC Milling Programming (2D & 3D) • Mold Flow Analysis & Optimization Technical Arsenal • CAD/CAM Software: SolidWorks, AutoCAD, DraftSight, SolidCAM (2D/3D CNC Milling) • Simulation & Analysis: Solidworks Plastic (Mold Flow) • Visualization & Prototyping: KeyShot (3D Rendering), 3D Printing/Slicing Software End-to-End Engineering & Manufacturing Expertise Having served as a Mold Shop Head, I possess a complete understanding of the manufacturing lifecycle. I don't just design parts; I engineer practical, producible, and maintainable solutions. My decades of hands-on shop floor experience ensure that every CAD model, technical drawing, and CNC toolpath I produce is optimized for production. I pride myself on: ✔ Reverse Engineering & Manufacturability Optimization: Highly skilled in evaluating and reverse engineering customer-provided designs—ranging from 2D PDFs and reference images to raw 3D solid and STEP files. When client designs present mold fabrication limitations, machining incompatibilities, or injection molding complications (e.g., poor draft angles, complex undercuts, wall thickness issues), I expertly redesign and optimize the geometry. This ensures the final product is fully manufacturable while strictly preserving the original design intent. ✔ Rapid Prototyping & Pre-Mold Validation: Expert in leveraging 3D printing to validate product designs prior to mold fabrication. I utilize rapid prototyping to quickly iterate based on customer feedback, verify the precise fitment of PCB components within enclosures, and evaluate the artistic appearance, ergonomics, and aesthetics of the final product. This significantly reduces time-to-market and prevents costly mold revisions. ✔ Production-First Design: Delivering highly accurate, shop-ready CAD designs that minimize revisions, reduce cycle times, and maximize machine uptime. ✔ Machine Setup & Advanced Troubleshooting: Extensive hands-on experience in plastic injection machine setup and mold installation. I expertly analyze and optimize processing parameters based on Material Data Sheets (MSDS/MDS), resin specifications, and specific mold configurations to eliminate defects and ensure smooth, repeatable production runs. ✔ Mold Repair Supervision & Defect Resolution: Expert in supervising mold maintenance and executing precision machining applications to rectify tooling issues. I conduct root-cause analysis on plastic part defects (e.g., flash, short shots, warpage, sink marks) and apply targeted machining, welding, and repair strategies to restore mold integrity and ensure optimal part quality. ✔ End-to-End Execution: Seamlessly transitioning from conceptual product design, reverse engineering, and 3D prototyping to mold flow analysis, CNC programming, and final machine validation. ✔ Technical Mentorship & Leadership: Fostering cooperative, cross-functional environments and guiding teams toward efficient, high-quality outcomes. ✔ Autonomous Reliability: Bringing the discipline, meticulous attention to detail, and proactive communication required to deliver flawless results in both on-site and remote engineering setups. Value Proposition Whether evaluating and optimizing flawed client designs, executing rapid prototypes for customer validation, designing complex injection molds, programming CNC toolpaths, optimizing molding parameters, or supervising critical mold repairs, I deliver precise, efficient, and high-quality engineering solutions tailored to exact production requirements. Let’s work together to bring your product ideas into reality.
