Who we are
Who we are
Precision Plastic Injection Molding, Since 1992.
PT Maindo Interbumi was founded in 1992 as a family-run plastic manufacturing business. Over three decades, we have grown from a traditional production house into a professionally managed facility — built on systems, not individuals. Today, we operate 10 injection machines alongside an active ISO Class 8 Cleanroom, serving four key industries: medical devices & healthcare, laboratory consumables, cosmetic packaging, and consumer goods packaging. Our transformation is ongoing — from 5R workplace discipline and Creative Kaizen to a Total Quality Control system where every operator owns quality at every stage. We are currently preparing for ISO 9001:2015 certification, reflecting our commitment to systematic, verifiable quality management.
