Dunia Polymer Extrusion Sdn Bhd

Dunia Polymer Extrusion Sdn Bhd is a Malaysian manufacturer of precision polymer extrusion and injection moulding products, established in 1995 and headquartered in Port Klang, Selangor — operating under triple certification IATF 16949:2016, ISO 9001:2015, and ISO 14001:2015 across two dedicated manufacturing plants totalling over 40,000 sq.ft. In the construction and mining machinery segment, Dunia Polymer supplies cabin sealing profiles, door and window gaskets, glazing seals, weatherstrip profiles, and custom-engineered polymer extrusions directly applicable as replacement components for excavator, wheel loader, bulldozer, and rigid dump truck cabins operating across Indonesian mine sites and infrastructure projects. As a Port Klang-based regional manufacturer, Dunia Polymer offers Indonesian heavy equipment distributors, mine site maintenance contractors, and construction machinery spare parts importers a quality-certified, short-transit supply alternative for cabin sealing and body trim components — with sea freight lead times from Port Klang to Tanjung Priok or Tanjung Perak significantly shorter than equivalent Chinese or European sources.

Products:

Cabin Door & Body Sealing Profiles — Construction & Mining Equipment

• Door and body seals — full perimeter cabin sealing profiles for noise, dust, and water intrusion prevention on construction and mining machinery cabins; compression and co-extrusion variants; replacement fitment for excavator, wheel loader, bulldozer, and motor grader cabins operating under tropical conditions and high-dust mine site environments across Kalimantan, Sulawesi, and Sumatra

• Trunk and hood seals — compression and bulb-type profiles for engine compartment cover and access panel sealing on heavy construction and mining equipment; custom cross-section to OEM specification

• Entrance and access door seals — heavy-duty perimeter sealing for operator cabin access doors on rigid dump trucks, articulated haulers, and mining excavators; high-cycle and vibration-resistant compound formulation

Glazing & Windscreen Sealing Profiles

• Glass run channels — cabin window sealing profiles providing precise dimensional guidance and weatherproof retention for fixed and sliding glazing on construction machinery operator cabins; IATF 16949:2016 compliant dimensional consistency

• Quarter window rubber — fixed-glass sealing profiles for side and rear cabin glazing on excavators, wheel loaders, and rigid dump trucks; UV-stable and ozone-resistant compound for prolonged tropical outdoor exposure

• Glazing seal profiles — structural glazing and window frame sealing for operator cabins and site office modules on active construction and mining sites

Weatherstrip & Environmental Sealing

• Weatherstrip and draft seals — door and panel perimeter sealing preventing dust, water, and particulate ingestion into operator cabins — critical on Indonesian coal and nickel mine sites where airborne mineral dust and tropical rainfall simultaneously challenge cabin integrity

• Expansion joint and panel covers — flexible profiles accommodating structural vibration and thermal movement in equipment body panels and cab assemblies

Custom Polymer Profile Engineering

• Bespoke cabin sealing profiles — full in-house engineering support from OEM drawing review and material selection through tooling fabrication, prototype trials, and production sign-off; custom cross-section extrusion for non-standard excavator, dump truck, or heavy plant cabin geometries; direct supply to Indonesian heavy equipment distributors and maintenance contractors maintaining active fleets

🏅 Triple certified: IATF 16949:2016 · ISO 9001:2015 · ISO 14001:2015

🏗️ 40,000+ sq.ft. across two dedicated plants — separate extrusion & injection facilities

🤖 IoT-integrated smart factory — real-time process monitoring & predictive maintenance

🚜 Cabin sealing & glazing profiles for excavators · wheel loaders · bulldozers · dump trucks

🌏 Port Klang-based — direct regional supply to Indonesia with competitive lead times

🏗️ High-frequency replacement category — cabin door seals, window gaskets, and weatherstrip profiles on Indonesian construction and mining
machinery degrade rapidly under simultaneous exposure to tropical UV radiation, high ambient humidity, airborne mineral dust, and the constant
vibration cycles of active mine site operation; seal failure directly results in operator cabin dust ingestion, water leaks, and ROPS/FOPS integrity
concerns — making quality-certified replacement seal supply a non-deferrable maintenance procurement for Indonesian fleet operators

🌏 Regional supply chain advantage — as a Port Klang-based manufacturer, Dunia Polymer offers Indonesian heavy equipment spare parts distributors
and maintenance contractors significantly shorter sea freight lead times than Chinese or European polymer seal suppliers; direct Port Klang →
Tanjung Priok (Jakarta) and Port Klang → Tanjung Perak (Surabaya) routing reduces inventory buffer requirements and enables faster emergency
replacement supply for active mine site and construction fleet maintenance programmes

🤝 Matched to the sourcing needs of Indonesian construction machinery spare parts distributors, mining fleet maintenance contractors, heavy
equipment dealers, and karoseri-adjacent workshop operators sourcing cabin door seals, glazing profiles, weatherstrip components, and custom
polymer extrusions for active excavator, wheel loader, bulldozer, and dump truck fleets across Java, Kalimantan, Sulawesi, and Sumatra
