Our Services Include
Mold Tryouts
Mold tryouts are a critical step in ensuring tooling is ready for production. At PMD, we perform detailed mold tryouts and injection tryout testing to evaluate how molds perform under real manufacturing conditions.
This process allows us to identify potential issues early, make necessary adjustments, and refine mold performance before full production begins. By conducting multiple iterations when needed, we help ensure molds produce consistent, high-quality parts while reducing the risk of costly delays later in the process.
Plastic Injection Molding
Our core service is plastic injection molding, supported by a wide range of equipment and technical expertise. We operate advanced machinery, including Van Dorn and Wittmann Battenfeld presses, allowing us to handle a variety of part sizes and production requirements.
Whether producing components for automotive plastic molding or other industries, we focus on precision, repeatability, and efficiency. Our team works to optimize cycle times, material usage, and part consistency to deliver reliable results at scale.
Mold Testing & Validation
Thorough plastic mold testing is essential for ensuring long-term production success. At PMD, we validate molds through controlled testing processes that evaluate material behavior, tooling performance, and part quality.
By testing molds under real production conditions, we can identify and correct issues early, improving performance and reducing defects. This approach ensures that molds are fully prepared for consistent output once production begins.
Short Run & Low Volume Production
Not every project requires high-volume production. PMD offers plastic molding short run production and low volume manufacturing to support prototyping, testing, and smaller production runs.
Short run production allows customers to validate designs, test market demand, and refine products without committing to large-scale manufacturing. This flexibility helps reduce upfront costs while maintaining high-quality standards.

Advanced Equipment & Automation
PMD utilizes advanced manufacturing technology to improve efficiency and consistency across all services. Our facility includes high-tonnage presses and automation systems designed to support complex production requirements.
Automation plays a key role in modern plastic molding manufacturing, particularly through the use of Cartesian robots. These systems improve precision, reduce cycle times, and ensure repeatable part handling throughout the molding process.
By integrating automation into our workflow, we are able to deliver more consistent results while maintaining flexibility across different project types.
Cost-Efficient Manufacturing Solutions
In today’s competitive environment, controlling production costs is essential. PMD helps customers achieve cost savings through efficient processes, optimized tooling, and strategic production planning.
Our approach to injection molding focuses on:
- Reducing material waste
- Improving cycle efficiency
- Minimizing rework through early testing
By combining mold tryouts, tool testing, and flexible production options, we help customers avoid costly mistakes and improve overall project efficiency.
