Resin Drying — ABS
Dryer settings and hopper sizing for ABS: 80 °C, ~3 h at -29 °C dewpoint.
ABS is the molder's all-rounder: amorphous (low, uniform shrink), tolerant melt window, paints and plates well. Splay from skipped drying is its signature defect. An undersized hopper 'dries' resin for however long the throughput allows, not what the datasheet demands — the hopper IS the residence timer.
Formula
Note: Starting-point process values — the resin grade's datasheet and an in-mold study govern. Verify with a gate-seal study and a cooling-time ladder on the actual tool.

About Resin Drying — ABS
Resin Drying — ABS computes the governing relationship hopper = throughput × residence ÷ bulk density × (1+margin) live as you type. ABS is the molder's all-rounder: amorphous (low, uniform shrink), tolerant melt window, paints and plates well. Splay from skipped drying is its signature defect. An undersized hopper 'dries' resin for however long the throughput allows, not what the datasheet demands — the hopper IS the residence timer. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Resin Drying — ABS
- 1Enter your values — Resin throughput, Residence required, Pellet bulk density, Hopper margin (sensible defaults are pre-filled).
- 2Read the live results: Resin in process, Hopper size needed.
- 3Check the "with your numbers" line to see hopper = throughput × residence ÷ bulk density × (1+margin) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Resin Drying — ABS?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula hopper = throughput × residence ÷ bulk density × (1+margin) with authoritative sources cited on the page (Resin supplier processing data sheets (per-grade values govern); Rosato, Injection Molding Handbook, 3rd ed.)
- ✓ABS is the molder's all-rounder: amorphous (low, uniform shrink), tolerant melt window, paints and plates well.
- ✓Niche-specific defaults give a meaningful worked answer the moment the page loads
Frequently asked questions
What formula does the resin drying — abs use?+
It evaluates hopper = throughput × residence ÷ bulk density × (1+margin), exactly as published.
