Process explainers, materials guides, quality system depth, written by people who run rubber parts manufacturing every day. EN/ID/JA on request.
Cold runner injection keeps the runner channels cool so uncured rubber stays usable for the next shot. Less waste, cleaner finish, more consistent cures.
A bonded rubber-metal assembly is one where the rubber is chemically and mechanically locked to a metal insert during the cure. Done right, the rubber tears before the bond fails.
The right rubber compound is the difference between a part that lasts and a part that fails. Match the compound to the fluid, the temperature, and the service life.
ISO 9001:2015 is the international quality management standard. What does it actually mean when your rubber parts supplier holds it, and what should you ask for beyond the certificate?
An engine mounting holds the engine to the chassis and isolates the chassis from engine vibration. Three things matter: stiffness, damping, durability.
From a drawing, a sample, or a concept: six steps from inquiry to first shipment. Tooling stays inside our walls.
Three of the most-requested seal categories: what each does, what they're made of, and how to pick the right compound for your fluid and temperature.
A buyer's checklist for evaluating Indonesian OEM rubber suppliers. Heritage, certification, named customers, vertical integration, trilingual support.
From a 200 sqm Slipi workshop in 2003 to a 10,000 sqm Cikupa factory today: the heritage behind every part we ship.
A walk through the Cikupa floor (compounding, mold making, molding, finishing, QC) with every step under one roof.
Hino, Suzuki, Honda, ROKI, APM, GSS, BMT, TACI, Enomoto Srikandi: the verified Japanese-OEM customer roster and what holds it together.
What actually happens on our QC bench every shift: Mooney, rheometer, tensile, ozone, aging, endurance, plus tailor-made customer test rigs.
Most of our molds are cut in-house. For extremely difficult or highly specialized parts, vetted external partners. A strategic choice, not a limitation.
High-voltage power silicon as the anchor capability, industrial seals for oil/gas/water/process equipment, EPDM and CR for marine: the non-automotive side of PBR's catalogue.
The bonded rubber-to-metal range: engine mountings, suspension bushings, dampers, vibration isolators, frame-rail bushings, and custom bonded assemblies.
The unbonded, all-rubber side of the catalogue: oil seals, water pump seals, drum seals, air-intake hoses, custom molded parts, and industrial sealing.
High-voltage power silicon parts (the anchor capability), industrial vibration isolators, marine gaskets, industrial seals for oil/gas/water utility/process equipment, and specialised custom molding for reliability-critical programs.
