Hand in Hand
for Success
Tradition
For over 60 years, our owner-operated family company has been a reliable partner to the plastics industry. Krumpholz offers performance based on tradition. Our competent and experienced employees are the foundation for our success, as well as our close integration of mold making and plastics engineering.
RESEARCH AND DEVELOPMENT
Our mission is to fulfill even special product requests from our customers with no restrictions. Our development department works closely with technical institutes and universities. We work with innovative design methods and use high-quality materials from major manufacturers. This allows us to significantly reduce tool wear in ongoing series production later on. Even before delivering our molds, we create functional prototypes and run systems under full load and series production conditions with technical support. This creates more security for the customer during the production process.
EXPERIENCE
Personal contact partners with years of experience and comprehensive professional expertise help every customer project run quickly, efficiently, and smoothly. Our flexible collection and delivery service using our own vehicle fleet and our exclusive Krumpholz emergency service, staffed 24 hours a day, 365 days a year, supplement our comprehensive range of services.
EFFICIENCY
Mold making and plastics engineering are not separate business areas at Krumpholz, but instead are linked closely on every level of our process. This allows us to develop and implement innovative, individual solutions very quickly. Our customers benefit from cost-efficient planning of processes, through to series production.
