In House Mold Design & Build

At Diverse Optics, quality in injection molding is paramount, which is why we fabricate all molds in-house. Our rigorous process guarantees each production mold is engineered to consistently produce up to a million high-quality optics. It begins by understanding each client’s specific needs, followed by a comprehensive review by our expert team to ensure performance. With over 35 years of experience creating hundreds of molds, our engineers have a deep understanding of the most effective techniques. Our mold makers ensure we meet our clients’ standards for quality, delivery, and value through detailed mold design reviews, mold flow analyses, and frequent updates.


Design Review and Tool Fabrication

The design phase involves meticulous reviews and refinements of both 3D and 2D tool designs until they meet our high standards. Upon client approval, we proceed with tool fabrication, prioritizing early delivery of critical components like optical pins and inserts. This allows us to begin working on the optical surfaces early in the build process, ensuring all parts are assembled, inspected, and ready for mold trials simultaneously, facilitating a smooth transition to production.

Society of Plastics Industry (SPI) Tooling Classifications

The Society of Plastics Industry (SPI) Tooling Classifications define standards for the durability and production capacity of molds used in plastic manufacturing. Diverse Optics adheres to these classifications to ensure optimal quality and lifespan for their molds

Class 101 Mold

Guaranteed for 1,000,000 + cycles

Ideal for extremely high production demands and are crafted from the highest quality materials to ensure durability and reliability.

Class 102 Mold

Guaranteed for 1,000,000 cycles

Suited for medium to high production levels and are robust enough to handle abrasive materials and demanding tolerances.

Class 103 Mold

Guaranteed for 500,000 cycles

These molds cater to low to medium production needs, balancing cost and performance effectively.

Class 104 Mold

Guaranteed for 100,000 cycles

These molds are intended for lower production volumes, offering a moderate price point for limited runs of non-abrasive materials.

Class 105 Mold

Guaranteed for 25,000 - 50,000 cycles

These molds are primarily used for prototype development and light production, providing an economical option for small batches.

Acceptance of Customer

Transferred Tooling


At Diverse Optics, we offer a specialized service known as transfer tooling, where we welcome customers to bring their existing molds from other suppliers. Unlike the unpredictable nature of using diverse molds, which can often result in quality inconsistencies, our expertise in precision polymer optics ensures that each mold is thoroughly evaluated and optimized for high-performance output.


When molds arrive, we conduct a detailed assessment to understand their current condition and identify any necessary enhancements. This evaluation includes documenting the mold's state with digital imagery and assessing its capabilities against your specific optical requirements. Based on this analysis, we recommend and implement on-site improvements to ensure the mold meets our stringent production standards.


Our depth of knowledge in polymer optics molding extends beyond basic injection molding techniques. We understand the intricate requirements of optical systems—from laser collimation and imaging to illumination—allowing us to refine and adapt molds for superior functionality. Bring your challenging molds to Diverse Optics, and let our expert team transform your production challenges into success stories.

Ensuring Longevity & Optimal Performance

Preventive maintenance is not just a part of our business—it's a cornerstone. By diligently maintaining your molds, we ensure smoother operations and extend their lifespan, which in turn facilitates the seamless production of millions of high-quality polymer optics. A well-maintained mold operates flawlessly, enhancing consistency and reducing production challenges. Conversely, neglecting mold care can lead to operational difficulties, introducing inconsistencies and variations that compromise product quality. Our commitment at Diverse Optics is to keep your molds performing at their best, maximizing both performance and durability through comprehensive and proactive maintenance.

Comprehensive Care for Optimal Mold Functionality

Diverse Optics is equipped with advanced tools like CNC and conventional milling machines, surface grinders, EDM, and lathes to ensure precise, real-time adjustments during mold trials. This setup guarantees rapid startup and strict adherence to delivery schedules.


Our "Evergreen" service demonstrates our dedication to maintaining your molds in optimal condition. It includes regular preventive maintenance, emergency repairs, and comprehensive upkeep according to industry standards. Through this service, we ensure your molds remain functional and efficient throughout their lifecycle, minimizing downtime and extending durability.

Proactive Measures for Uninterrupted Production

At Diverse Optics, risk prevention is fundamental to our polymer optics operations. We begin with a robust preventive maintenance program to keep your molds in peak condition, ensuring they are always production-ready. However, manufacturing realities mean that sometimes, even the best-prepared plans face unforeseen issues.


Understanding that risk tolerance can vary based on the customer's specific industry and budget, we offer tailored risk management strategies. These include comprehensive risk assessments and a variety of mitigation options to match your needs. Options may range from maintaining a strategic inventory to ensure continuous supply, utilizing diamond turning for precise optics production, keeping critical spare mold components on hand, or even creating a complete backup mold for critical projects. Our goal is to provide peace of mind, ensuring your operations run smoothly no matter the circumstances.
