From Concept to Production-Ready Tooling
We engage early in the lifecycle to turn complex parts and assemblies into robust plastic designs and tools that will run the way engineering intended.
Our teams focus on manufacturability, interchangeability, and high performance over the life of the program while building tools that support stable downstream production.
Piece-part design support, DFM simulation, and engineering for complex plastic components.
Design and build of multi-cavity precision molds with uncompromising tolerances and repeatability.
Troubleshooting and transfer of underperforming tools that are putting quality, uptime, or cost at risk.
Mold Making &Tooling Capabilities
Janler's deep expertise and range of capabilities delivers complex molds and tools that run reliably and at scale. From hot runner/runnerless molds to LSR molds and beyond, we've got you covered.
OEM Programs Where the Mold Has to Perform
We partner with engineering, tooling, R&D, and operations teams where mold quality directly affects validation, line speed, uptime, and long-term output. Typical Programs Include:
Medical devices, diagnostic equipment, and dental products requiring tight tolerances and high production
Food and beverage, and CPG packaging where tool quality and consistent output drives line speed
Industrial and specialty applications with complex requirements and demanding production environments.
Industrial and specialty applications with complex requirements and demanding production environments
We’re Plastics Engineers With Deep Expertise
70+ years of plastics engineering for complex tooling programs.
Tools built for longevity, easy maintenance, and predictable performance.
For outsourcing OEMs, Uniphase & Janler provide accountability for complex programs.
"As a medical device manufacturer, we value tooling partners who combine deep mold-building experience with practical engineering collaboration. Janler / Uniphase has consistently demonstrated strong technical capability, responsive communication, and a willingness to work through complex tooling challenges with our team."
"Their support has included design reviews, material and steel-selection discussions, mold-flow evaluation, sampling support, metrology coordination, and practical recommendations that help move projects forward."
"We have partnered with this tool shop for over 25 years, and throughout that time they have consistently demonstrated exceptional technical competence in precision mold design, tooling manufacturing, and injection molding process development."
"Their engineering team has a strong understanding of Design for Manufacturability (DFM), mold flow considerations, cooling optimization, venting, gating strategies, and robust tool construction, enabling them to deliver tooling that meets demanding quality and production requirements. Beyond tool fabrication, they bring valuable expertise in molding process optimization, allowing for faster qualification, improved process capability, and stable long-term production performance. They are also proactive in evaluating new manufacturing technologies and are highly collaborative when developing innovative solutions to optimize part design, tooling performance, and overall manufacturing efficiency. Their technical knowledge, responsiveness, and commitment to continuous improvement have made them a trusted engineering partner for more than two decades."
"They bring much more than tooling expertise—they possess a deep understanding of processing and process development."
“I have worked with the Janler team for more than 10 years across numerous tooling projects, many involving highly engineered resin applications with 32-cavity and larger molds. What has consistently set Janler apart is their commitment to continuous improvement throughout the entire tool design process. They bring much more than tooling expertise—they possess a deep understanding of processing and process development, making them an exceptionally skilled and valuable partner. No matter how complex the challenge, we have always been able to work through it together because Janler truly believes in their products and is committed to the success of their customers. Their technical knowledge, collaboration, and dedication have made them a trusted partner for our business.”
