Vertical integration isn't a buzzword on the Cikupa floor — it's the actual layout. From raw polymer to packed part, every step happens inside our walls. Here is what that looks like in equipment terms.
Compounding
The compounding line includes 2 open roll mixing mills (for finishing, color matching, and trials), a 55-litre internal kneader (medium-batch production compounding), a 75-litre internal kneader (larger production volumes), 2 compound cooling units, an automatic chemical weighing system, and a Barwell automatic rubber preformer for consistent shot-weight pre-forms. Compounds are mixed from polymers sourced from Lanxess, ExxonMobil, and Sumitomo.
Mold manufacturing — in-house
Most of our competitors outsource mold making. We don't. CNC mold milling cuts production-grade steel molds on multi-axis. An FDM 3D printer produces rapid prototype tooling for early fit checks and fixture trials. The mold engineer sits feet from the press operator — iteration is direct.
Molding — 65 machines, four methods
- 9 cold runner injection presses — lead technology, lowest waste
- 46 compression machines — for low-cavity, high-volume, or complex geometries
- 4 hot runner injection presses
- 3 vacuum molding presses — for void-sensitive parts
- 3 post-cure ovens — for silicone and FKM finishing
- Supporting 60-ton and 250-ton presses visible on the floor
Metal processing and assembly
For bonded assemblies and inserts: 4 CNC lathes, 3 70-ton power presses, 1 hydraulic assembly press, 2 wheel brushing stations.
Finishing
High-speed deflashing, nitrogen deflash tumbler, laser marking, laser cleaning. Parts leave the floor clean and labeled.
QC laboratory
Mooney viscometer, tensile strength tester (including UCAN tensometers), rheometer, ozone tester, aging tester, endurance tester, measuring microscope, plus tailor-made customer-specific test machines built to PPAP-level customer programs.
What it means for buyers
One roof, one accountable team, one quality system. No shipped intermediates, no third-party tool shop, no third-party compounding. Lead time stays short, traceability stays tight, IP stays inside.
