Complete Cleanroom & Filtration Solution for Injection Molding Workshops
Sep 05,2026
1. Why Clean Environment Matters for Injection Molding
Dust, static electricity, temperature and humidity fluctuations easily cause injection molding defects such as scratches, bubbles and low transparency, resulting in high rejection rates and unqualified product audits. For medical, food-grade, electronic and automotive plastic parts, a standardized clean workshop is essential to meet ISO 7/8 cleanliness standards and ensure stable mass production.
A qualified injection molding clean workshop depends on two core systems: dust-proof insulated cleanroom panels and graded HVAC air filtration systems.
2. Cleanroom Sandwich Panel Enclosure System
Traditional walls accumulate dust and shed particles, failing clean production demands. Our customized cleanroom sandwich panels are tailored for injection molding workshop construction and renovation, with outstanding comprehensive performance:
- Premium Material: Double-sided color steel/stainless steel with magnesium oxide or rock wool core; seamless splicing leaves no dust hidden gaps, enabling easy daily cleaning.
- A-Class Fire Resistance: Effectively avoids fire risks from plastic raw materials and hot-melt equipment, complying with industrial fire safety standards.
- Stable Insulation: Controls indoor temperature and humidity, prevents material moisture absorption and product deformation, and boosts production yield.
- Fast Installation: Modular prefabricated panels shorten construction cycles and help factories launch production faster.
Widely applied in precision molding, medical plastic, electronic component workshops and dust-free packaging areas, the panels build a stable sealed foundation for clean production.
3. Multi-Stage HVAC Filtration Solution
Our graded filtration system removes floating dust, fibers and volatile fine particles, matching different cleanliness requirements of injection molding workshops:
G4 Pre-filter (Primary Filtration)
Installed at fresh air inlets to intercept large particles and lint, protecting mid/high-efficiency filters and extending their service life.
F8 Pleated Filter (Medium Filtration)
Mounted in air ducts to filter fine suspended particles, stably maintaining basic workshop air cleanliness.
HEPA Filter & FFU Unit (High-efficiency Filtration)
H13/H14 HEPA filters achieve 99.97% filtration efficiency for 0.3μm particles. Ceiling FFU units provide local laminar airflow for high-precision molding zones, eliminating particle pollution above operating stations.
4. Standard Workshop Environmental Parameters
Our integrated solution helps workshops reach stable standard operating conditions:
- Temperature: 18–26℃ (constant)
- Relative Humidity: 30%–50% RH (anti-static & moisture-proof)
- Positive pressure design: Blocks external dust infiltration
- Air change rate: Compliant with ISO 7/8 cleanroom standards
5. Our Core Advantages
As a professional manufacturer of cleanroom sandwich panels and HVAC filters, we provide one-stop services including customized design, production and supporting installation. Customers avoid multi-supplier coordination, with better-matched systems, more stable cleanliness performance and higher cost performance. Our solutions fit small renovations, medium upgrades and large new cleanroom projects.
6. Summary
A dust-free, constant-temperature injection molding workshop is key to improving product qualification rates and qualifying high-end supplier audits. Our matched panel and filtration solutions deliver reliable, cost-effective clean environment support for all plastic molding scenarios.
