Precision Injection Molding
Japanese all-electric and Haitian injection machines, specialized molding of precision small and medium-large parts
Injection Overview
Japanese All-electric · Haitian · Precision Small & Medium-large Molding System
UDD deploys Japanese all-electric and Haitian injection machines to cover full-size molding needs from precision small parts to medium-large parts. The high-response, low-inertia injection control of all-electric machines suits micro connectors and earphones, while Haitian machines handle stable mass production of medium-large automotive and appliance parts.
All-electric Machines
High-precision injection control, ideal for precision small parts like micro connectors, earphones and networking that demand strict dimensions and appearance.
Haitian Machines
Stable, efficient medium-large tonnage models for batch molding of automotive, appliance and medium-large structural parts.
Molding System
From material drying, mold temperature control and injection process to automatic pick-up, inspection and packaging, UDD builds a complete precision injection molding system.
Synergy Advantage
Seamless connection with in-house molds, spray and silk screen, SMT and assembly packaging for one-stop delivery.
