Plants running specific injection molding press brands often want to know whether a third-party hydraulic quick mold change system integrates cleanly with their installed equipment. The short answer: yes, on every major OEM. Engel, Arburg, Haitian, Chen Hsong, JSW, Sumitomo Demag — KINGHOU has installed hydraulic mold clamp retrofits on all of them. The longer answer involves OEM-specific platen geometry, control interlock differences, and electrical service variations. This article documents the OEM-specific considerations for hydraulic mold clamp retrofits on the four most common injection press brands KINGHOU sees in customer installations.

Engel (Austria) — Hydraulic Mold Clamp Retrofit Notes
Engel injection molding presses use a tie-bar architecture with platen face geometry that varies by series. The Victory, Duo, e-mac, and e-motion lines each have slightly different T-slot patterns and platen face areas. KINGHOU hydraulic mold clamp retrofits on Engel presses typically need:
- Custom clamp mounting brackets to align with Engel T-slot spacing (varies 100-150mm)
- External press control interlock — Engel CC300 / CC200 controls accept dry-contact clamp engagement signal via aux I/O
- HPU placement away from Engel tie-bar zone — typically 1.5m clearance
- For all-electric Engel e-motion presses: standard hydraulic mold clamp with independent HPU works fine; no integration with press hydraulic system needed
Typical Engel retrofit timeline: standard weekend shutdown. No press-side modifications required beyond the aux I/O wiring.
Arburg (Germany) — Hydraulic Mold Clamp Retrofit Notes
Arburg Allrounder series presses are well-engineered with standardised T-slot geometry across most tonnage ranges. KINGHOU hydraulic mold clamp retrofits on Arburg are among the cleanest installations:
- Standard T-slot patterns accept KINGHOU clamp mounting without custom brackets in 80% of cases
- Selogica control system accepts external interlock via standard digital input
- Existing Arburg utility connection points work for HPU electrical and compressed air routing
- Mold-side clamp slot machining: typically half-shift per mold on plant CNC
Arburg retrofits typically complete fastest among the four major OEMs — standardisation pays back in installation time.

Haitian (China) — Hydraulic Mold Clamp Retrofit Notes
Haitian is the largest installed injection press base in China and a growing presence globally. Haitian Mars, Jupiter, Saturn, Venus series each have slightly different platen geometry. KINGHOU has installed more hydraulic mold clamp retrofits on Haitian than any other OEM (geographic proximity is part of the reason):
- Mars series (general purpose): standard T-slot, straightforward retrofit
- Jupiter series (high tonnage 800T+): wider clamp count needed due to larger platen, otherwise standard
- Saturn series (two-platen): special clamp positioning to avoid tie-bar interference
- Venus series (all-electric): same as Mars retrofit pattern
- Haitian native control accepts external clamp interlock via standard digital input
KINGHOU spare parts and engineering support for Haitian retrofits are typically delivered next-day from KINGHOU Suzhou facility.
Chen Hsong (Hong Kong / China) — Hydraulic Mold Clamp Retrofit Notes
Chen Hsong injection presses are common in Southeast Asia and increasingly in North America. The JM series and Supermaster series have well-documented T-slot patterns:
- JM series (general purpose 50T-650T): standard small-platen retrofit
- Supermaster series (800T+): standard high-tonnage retrofit with attention to platen flatness on older units
- Chen Hsong CPC control: external clamp interlock supported via aux digital input
- Plant maintenance staff familiarity with Chen Hsong control panels makes operator SOP rollout simpler than with European OEM brands

Other OEMs Covered by KINGHOU Hydraulic Mold Clamp Retrofits
- JSW (Japan): standard retrofit pattern with attention to JSW platen face hardness
- Sumitomo Demag: all-electric and hybrid press retrofits, both supported
- KraussMaffei: Multi-platen press retrofits including stack-mold configurations
- Nissei: standard injection retrofit
- Toshiba Machine / Shibaura: standard injection and die casting retrofits
- Negri Bossi: standard injection retrofit
- Husky: heavy-tonnage retrofits, custom clamp force for very large mold inventories
What KINGHOU Needs to Quote an OEM-Specific Retrofit
- Press OEM and series (e.g. Engel Victory 800T)
- Year of manufacture (older units may need platen face dressing)
- Photo of existing T-slot pattern (mobile photo is sufficient)
- Mold inventory list with weights and clamp pattern
- Press control I/O availability for clamp engagement interlock signal
- Available three-phase electrical capacity at the press location

Conclusion
Hydraulic mold clamp retrofits work cleanly across all major injection press OEMs. The variance lives in T-slot geometry, control interlock interface, and platen face condition on older units — all surveyable in a half-day. KINGHOU has retrofitted Engel, Arburg, Haitian, Chen Hsong, JSW, Sumitomo Demag, KraussMaffei, and others. The clamp engineering is OEM-agnostic; the install detail is OEM-aware.
