How to Choose the Right Multihead Weigher for Your Production Capacity?

    For manufacturers in food, pharmaceuticals, hardware, or consumer goods, selecting a multihead weighed that matches your production capacity isn't just about "picking a fast machine"—it's about balancing speed, accuracy, space, and cost to avoid overinvesting in unused capacity or struggling with bottlenecks. UUPAC's multihead weigher category offers models ranging from compact 4-head units to high-capacity 10-head systems, each designed for specific output needs. This guide will help you identify which model aligns with your daily production goals, product type, and facility constraints.

Step 1: Calculate Your Actual Production Capacity Needs

    Before browsing UUPAC's multihead weigher lineup, start with a clear number: how many weighments do you need per minute (WPM)? This depends on two key factors:

1. Your daily production target (e.g., 50,000 packaged units per 8-hour shift).
2. Your packaging machine speed (e.g., a VFFS machine that seals 60 bags per minute—your weigher must match or exceed this to avoid bottlenecks).

    Once you have your WPM, use UUPAC's model range to narrow down options—we've grouped our multihead weighers by "capacity tiers" to simplify your choice.

Step 2: Match Your WPM to UUPAC's Multihead Weigher Tiers

    UUPAC's multihead weigher category is designed to cover three core production scenarios: small-batch/mid-volume, high-volume, and specialized high-capacity operations. Below is how to align each tier with your needs, plus key model recommendations from our category page.

• Tier 1: Small-Batch & Mid-Volume Operations (30–85 WPM)

• Who This Is For:

• Small-scale food processors (e.g., local snack factories, artisanal nut roasters).
• Businesses with compact facilities (e.g., 50–100 sq. meters of production space).
• Product types: Lightweight, small-volume items (3–300g), such as spices, candy, pet treats, or small hardware components (screws, washers).

• Key UUPAC Model: 4-Head 0.5L High-Speed Linear Weigher (TY-A-MX-4-5)

    From UUPAC's multihead weigher category, this model is built for space-saving efficiency without sacrificing performance:

• Speed: Up to 85 WPM—perfect for 20,000–40,000 units per 8-hour shift.
• Capacity: 0.5L hoppers (ideal for small, lightweight products) with a max weighing limit of 300g per hopper.
• Space Fit: Dimensions of 1,086(L)X710(W)X898(H)mm and 91kg net weight—fits under low ceilings or beside existing packaging lines.
• Why It Works: The 4-head design balances speed and simplicity; it's easy to clean (IP65 waterproof) and supports quick product changeovers (99 preset programs) for brands with 5–10 SKUs.

• Tier 2: High-Volume Operations (60–120 WPM)

• Who This Is For:

• Medium-to-large food manufacturers (e.g., cereal producers, bulk nut packagers, frozen food facilities).
• Businesses with consistent high output (40,000–80,000 units per 8-hour shift).
• Product types: Medium-to-large volume items (50–1,000g), such as granola, rice, dried fruit, or herbal medicine slices.

• Key UUPAC Models: 10-Head 1.6L/2.5L Computer Weighers (TY-A-M/P10-16 / TY-A-M/P10-25)

    These are the workhorses of UUPAC's multihead weigher category, designed for reliable high-volume performance:

• Speed: Up to 60 WPM (1.6L) and 60 WPM (2.5L)—with 10 independent hoppers that combine weights to hit target measurements in seconds (adds flexibility for variable product sizes).
• Capacity: 1.6L hoppers (max 1,000g per hopper) for medium items; 2.5L hoppers (max 1,500g per hopper) for larger, denser products (e.g., whole almonds, pasta).
• Accuracy: ±0.1g error margin—critical for pre-portioned products sold by weight (avoids regulatory fines for underpacking or material waste from overpacking).
• Why It Works: The 10-head design handles peak production periods without slowdowns; it also supports blended product weighing (e.g., mixed nuts) and integrates seamlessly with high-speed packaging lines (e.g., automatic pouch fillers).

• Tier 3: Specialized High-Capacity Operations (100–150+ WPM)

• Who This Is For:

• Large-scale industrial manufacturers (e.g., global snack brands, bulk chemical producers).
• Facilities with 24/7 production lines or ultra-high daily targets (80,000+ units per shift).
• Product types: High-density or large-volume items (1kg–5kg), such as industrial hardware, large bags of fertilizer, or bulk pet food.

• Key UUPAC Models: Custom 12–16 Head Multihead Weighers (Inquire via Category Page)

    For operations that need more than 10 heads, UUPAC offers custom-configured multihead weighers (available to quote via our multihead weigher category page):

• Speed: Up to 150 WPM—with 12–16 hoppers and reinforced motors for continuous 24/7 use.
• Capacity: 3–5L hoppers (max 5kg per hopper) for heavy or bulky products.
• Durability: SUS 316 stainless steel construction (resists corrosion for chemical or wet products) and industrial-grade load cells (handles constant use without accuracy drift).
• Why It Works: Customizable to your exact line—we'll match the weigher's speed to your packaging machine, add extra hoppers for blended products, or integrate with your factory's IoT system for real-time production tracking.

• Step 3: Avoid Common Capacity Mistakes

Even if you pick the right WPM tier, these errors can ruin your investment—here's how to avoid them:

1. Don't Overbuy for "Future Growth":

A 16-head weigher is unnecessary if you only need 60 WPM today. UUPAC's multihead weigher category includes modular models (e.g., the 10-Head 1.6L) that can be upgraded with extra hoppers later—save money now and scale when needed.

2. Don't Ignore Product Density:

A 4-head weigher might hit 85 WPM for lightweight candy, but it will slow down for dense products (e.g., metal bolts). For heavy items, opt for larger hoppers (e.g., 2.5L instead of 0.5L) to reduce the number of "refills" per weighment.

3. Match Weigher Speed to Your Slowest Machine:

Your weigher can't fix a slow packaging machine. If your VFFS machine only does 50 WPM, a 120 WPM weigher will sit idle—use UUPAC's category page to filter models by speed that aligns with your existing equipment.
