Special oil filter for die casting machine

• Specialized oil filter for die-casting machine hydraulic systems: compatible with cold/hot chamber machines (50-5000T), targeting aluminum/zinc alloy debris, metal shavings, and oil oxidation residues.

• Features 5-20μm multi-stage filtration: 5μm precision for high-pressure servo systems (prevents valve blockage), 20μm for general hydraulic circuits (reduces pump wear).

• Achieves 50-200L/min flow rate: matches small 50T zinc machines (50L/min) to large 5000T aluminum cookware machines (200L/min), no hydraulic flow loss.

• Integrates die-casting-specific design: stainless steel 316L filter element (resists hydraulic oil corrosion), pressure differential alarm (triggers at 0.3MPa clogging), and quick-change cartridge (swap in 5 minutes).

• Extends hydraulic oil service life by 3x (from 3 months to 9 months) and reduces hydraulic component replacement by 60%, cutting B2B die-casting factory maintenance costs.

• Complies with global standards (ISO 9001, CE, DIN 24550) and supports inline installation (fits most die-casting machine oil circuits), suitable for export to auto parts, cookware, and industrial component factories.

Visually, the filter has a sleek stainless steel housing—compact (300×150×400mm for 100L/min model) to fit die-casting machine oil tanks without extra space. When you touch the filter housing (even after 8 hours of operation), it feels cool (≤40℃) thanks to the built-in heat dissipation fins—unlike generic filters that overheat to 60℃ and risk oil degradation. The quick-change cartridge has a textured rubber grip that’s easy to twist (no slippery tools) and a clear pressure gauge on top—green (0-0.2MPa) means clean, red (>0.3MPa) means change. During operation, the filter emits a soft “whoosh” of oil flow (55 decibels)—quieter than a hydraulic pump—so it doesn’t add to workshop noise. You’ll notice the filtered oil is clear and odorless (no metallic scent), unlike unfiltered oil that’s cloudy with aluminum dust. After 9 months, oil analysis shows only 0.02% debris content (vs. 0.15% with generic filters)—the factory’s pump replacement dropped to 1/year, and oil changes extended to 9 months. Every detail—from the corrosion-resistant inlet/outlet (1.5” threaded) to the magnetic pre-filter (catches iron debris)—is designed to protect die-casting hydraulic systems, cut costs, and minimize downtime for B2B users.

• 5-20μm Multi-Stage Filtration Cuts Pump Wear by 60%: The filter’s dual-layer element (primary 20μm stainless steel mesh + secondary 5μm glass fiber) removes 99.8% of debris—including fine aluminum/zinc particles that generic filters miss. A Chinese auto bracket factory reduced hydraulic pump replacements from 3/year to 1/year, saving \(12,000 annually. The 5μm precision is critical for servo valves (sensitive to 10μm+ debris)— a Vietnamese die-casting factory reduced valve failures from 4/year to 0.5/year, avoiding \)24,000 in emergency repairs. For high-pressure systems (31.5MPa), this filtration ensures valve response time stays within 0.1 seconds (no lag that causes die-casting part defects).

• **3x Oil Life Extension Saves \(43,200/Year**: By removing oxidation residues and metal debris, the filter extends hydraulic oil service life from 3 months to 9 months— a 500T die-casting factory using 200L/month reduced annual oil costs from \)57,600 to \(19,200, saving \)38,400. The filter also has an oil moisture absorber (built into the cartridge) that reduces water content to <0.05% (vs. 0.15% with generic filters)—prevents oil emulsification (a major cause of pump damage). For factories in humid regions (e.g., Southeast Asia), this moisture control adds 2 months to oil life, saving an extra $9,600/year.

• Quick-Change Cartridge Cuts Maintenance Time by 75%: The filter’s tool-free cartridge swap takes 5 minutes (vs. 20 minutes for generic filters with bolts). A Brazilian cookware factory with 10 die-casting machines reduced weekly maintenance time from 200 minutes to 50 minutes, freeing teams for other tasks. The cartridge has a built-in O-ring (nitrile rubber, oil-resistant) that seals automatically—no messy gaskets or oil spills. A U.S. industrial component factory reported zero oil leaks during changes (vs. 20% leak rate with old filters), avoiding $5,000/year in oil waste and floor cleanup.

• 1.6-3.0MPa Pressure Resistance Matches Die-Casting Systems: The filter’s stainless steel 304 housing withstands 3.0MPa (higher than most die-casting hydraulic systems’ 25MPa max pressure)—no bursting risk. The pressure differential alarm (visual + audible) triggers at 0.3MPa, so operators change cartridges before clogging causes flow loss. A German die-casting factory using 3 filters avoided 12 hours of unplanned downtime/year (vs. 48 hours with generic filters), retaining a $1.2M order that would have been delayed. The filter also has a bypass valve (opens at 0.4MPa) that prevents oil starvation—critical for continuous production lines.

• Magnetic Pre-Filter Catches Iron Debris (Extra Protection): The integrated magnetic ring around the inlet captures 90% of iron debris (e.g., from pump wear) before it reaches the main filter—extending cartridge life by 20%. A Chinese zinc die-casting factory reduced cartridge changes from 4/year to 3.2/year, saving $1,600 in replacement costs. The magnet is removable (for cleaning) and has a corrosion-resistant coating—works with all hydraulic oil types (mineral, synthetic, biodegradable) without rusting. For factories with mixed metal die-casting (aluminum + iron parts), this pre-filter prevents cross-contamination of oil systems.

• Cold Chamber Aluminum Machines (500-5000T): Ideal for high-volume aluminum production. The 5μm filtration protects servo hydraulic systems (sensitive to debris), and 200L/min flow matches large machine oil circuits. A Chinese 1000T cookware machine factory reduced oil changes from 3 to 9 months, saving $38,400/year. The magnetic pre-filter catches iron debris from pump wear, extending cartridge life by 20%.

• Hot Chamber Zinc Machines (20-100T): The 50-100L/min flow fits small zinc machines, and stainless steel 304 housing resists zinc-contaminated oil corrosion. A Mexican zinc handle factory reduced valve failures from 3/year to 0.5/year, avoiding $18,000 in repairs. The quick-change cartridge (5 minutes) minimizes downtime for 2-shift production.

• High-Pressure Die-Casting Machines (31.5MPa): The 3.0MPa pressure resistance and bypass valve ensure stable oil flow during high-pressure shots. A German auto parts factory using 31.5MPa machines reported zero filter-related downtime in 1 year, meeting BMW’s strict production schedules.

• Humid-Environment Factories (Southeast Asia): The built-in moisture absorber keeps oil water content <0.05%, preventing emulsification. A Thai die-casting factory extended oil life by 2 months (vs. dry regions), saving $9,600/year and avoiding pump rust.

• Multi-Stage Filtration Principle:

1. Magnetic Pre-Filter: A neodymium magnet around the inlet captures iron debris (e.g., pump wear particles) — prevents 90% of iron from reaching the main element.

1. Primary Coarse Filtration (20μm): Stainless steel mesh removes large aluminum/zinc chunks (10-20μm) — protects the fine filter from clogging quickly.

1. Secondary Fine Filtration (5μm): Glass fiber layer traps fine particles (5-10μm) — critical for servo valves and precision pumps.

1. Moisture Absorption: Activated alumina in the cartridge absorbs water vapor — keeps oil moisture <0.05%.

• Inline Installation Steps (30 Minutes for 2 Technicians):

1. Shut down the die-casting machine’s hydraulic system and drain 5L of oil (to avoid spills).

1. Cut the oil return line (size matches filter inlet/outlet: 1.0”-2.0”) and install the filter with threaded connections (use Teflon tape for sealing).

1. Mount the filter on a stable bracket (included) — ensure the pressure gauge is visible and the cartridge is easy to access.

1. Refill oil, start the system, and check for leaks (use soapy water on connections) — no bubbles mean tight.

1. Reset the pressure differential alarm (press the button on the gauge) — ready to use.

• Daily Checks (2 Minutes/Shift):

1. Pressure Gauge Inspection: Check if the needle is in the green zone (0-0.2MPa) — red zone (>0.3MPa) means replace the cartridge immediately.

1. Leak Test: Visually inspect inlet/outlet connections for oil drips — wipe up small spills and tighten if needed (use a wrench, not pliers).

1. Oil Color Check: Look at the filter’s sight glass (if equipped) — clear oil = good, cloudy oil = check cartridge (even if gauge is green).

• Weekly Maintenance (15 Minutes):

1. Clean the Magnetic Pre-Filter: Unscrew the magnet from the inlet, wipe off iron debris with a rag, and reinsert — prevents debris buildup that reduces flow.

1. Check Bypass Valve Function: Manually trigger the valve (press the test button) — listen for a “click” (means it opens/closes properly) — critical for preventing oil starvation.

1. Record Pressure Data: Log the gauge reading in a spreadsheet — track how fast the filter clogs (helps predict cartridge changes).

• Monthly Maintenance (30 Minutes):

1. Cartridge Replacement (When Gauge is Red):

• Twist the old cartridge counterclockwise (use the rubber grip) and dispose of it (recyclable stainless steel parts).

• Remove the new cartridge’s plastic seal, align the tabs, and twist clockwise until it clicks (tight, no overtight).

• Press the gauge’s reset button — needle returns to 0MPa.

1. Oil Sample Analysis (Every 3 Months):

• Take a 100mL oil sample from the filter’s sampling port (included) and send it to a lab — test for debris content (<0.05% is good) and viscosity (should be within ISO VG specs).

1. Filter Housing Cleaning: Wipe the housing with a damp rag (no harsh chemicals) — removes aluminum dust that blocks heat dissipation.

• Flow Rate Adjustment: Increase to 300L/min (for 5000T+ large machines) or decrease to 30L/min (for 20T small zinc machines). A Chinese 6000T aluminum wheel machine factory ordered 300L/min filters—flow loss dropped to <5% (vs. 15% with generic filters), ensuring stable die-casting pressure.

• Material Upgrade to 316L Stainless Steel: For factories using corrosive synthetic oil or in coastal areas (salt air), 316L housing resists rust 5x better than 304. A U.S. coastal die-casting factory used 316L filters—housing lifespan extended from 5 years to 10 years, saving $6,000 in replacement costs.

• Smart Monitoring Integration: Add a wireless pressure sensor (connects to MES) that sends alerts to your phone/PC when the filter clogs. A European auto parts factory used this—maintenance teams changed cartridges during breaks (no production stop), reducing downtime by 4 hours/year.

• High-Temperature Version (Up to 120℃): For die-casting machines with hot oil circuits (e.g., 80-120℃), the filter uses heat-resistant seals (Viton) and glass fiber (stable at 150℃). A Thai factory with hot-chamber zinc machines avoided oil degradation (common with generic filters at 80℃), extending oil life by 3 months.

• Warranty Coverage: 2-year warranty for the stainless steel housing (covers rust, cracks); 6-month warranty for filter cartridges (covers manufacturing defects). For high-volume factories, extend cartridge warranty to 9 months (50% extra cost)— a Chinese 500T factory used this to reduce cartridge costs by $1,200/year.

• 24/7 Technical Support: Our team of 3 hydraulic filtration engineers (8+ years in die-casting) offers round-the-clock help via phone/WhatsApp/video. For urgent clogging (e.g., during a rush order), we respond within 15 minutes—85% of issues resolved remotely (e.g., guiding bypass valve use to keep production running).

• Spare Parts Supply: Stock cartridges, O-rings, and pressure gauges in 3 regional warehouses (China, Germany, U.S.). 24-hour delivery to major industrial hubs— a Brazilian factory received replacement cartridges in 18 hours, minimizing downtime to 1 shift.

• On-Site Training: Free 1-day training for your maintenance team—covers filter installation, cartridge replacement, and oil analysis interpretation. A Vietnamese factory’s team reduced filter-related errors by 80% after training, mastering skills like “magnetic pre-filter cleaning for zinc machines.”

• Specialization in Die-Casting Oil Filtration: We don’t make generic industrial filters—we focus exclusively on die-casting hydraulic systems, understanding their unique debris (aluminum/zinc), pressure (up to 31.5MPa), and oil needs (ISO VG 32/46/68). Our R&D team tests every filter with real die-casting oil (contaminated with aluminum dust) to solve actual pain points.

• Proven B2B Track Record: Over 150 die-casting factories in 32 countries use our filters, including suppliers to Ford, IKEA, and Bosch. A Chinese auto parts factory increased annual revenue by $800,000 after reducing downtime by 48 hours/year (thanks to our filter’s reliability).

• Transparent ROI for B2B Operations: We provide a customized ROI calculator (based on your oil costs, pump/valve replacements, and downtime). Most clients recoup investment in 8-10 months—for a 500T die-casting factory, this means $60,000 in 5-year savings (oil + parts + downtime).

• Die-Casting Expertise: We offer free oil analysis consultations (send us a sample, we’ll interpret results) and filter selection guidance (e.g., “5μm for servo machines, 20μm for general circuits”). A U.S. cookware factory used our advice to choose the right flow rate—flow loss dropped to 3%, improving die-casting part consistency.

• Flexible Lead Times: Standard filters (50-200L/min, 304 stainless steel) are in stock (delivery 7-10 days). Customized models take 12-15 days—40% faster than competitors (25+ days). A Mexican zinc factory received 30L/min custom filters in 14 days, meeting a $500,000 rush order.
