Why San’yuan’se Colorimeter Is Ideal For Plastic & Masterbatch Industry

Plastic color masterbatch and injection molding production face many common color problems. SANYUANSE professional colorimeter and spectrophotometer provides full color measurement solution. It helps you finish fast color matching, precise color calibration and strict quality inspection.

Main Industry Pain Points We Solve

1. Big error from human visual color check

Workers judge color by eyes. Results change with light source, angle and personal experience. It causes high return rate and customer complaint.
SANYUANSE colorimeter uses standard D65 light source. It turns color into accurate Lab numerical data. No subjective deviation anymore.

2. Slow color mixing and high raw material loss

Traditional manual color testing needs repeated trial production. It wastes lots of color masterbatch and production time.
Our device can read standard color data directly. It guides you to adjust formula quickly. It greatly shortens color matching cycle and reduces production cost.

3. Unstable color between different batches

Different batches of plastic pellets and masterbatch always have color shift. Final injection products look inconsistent.
You can set fixed color standard with SANYUANSE tester. Every batch raw material and finished goods can be compared. It keeps mass production color stable all the time.

4. Hard to meet high-end brand color requirement

Many global clients ask for strict unified color standard and color difference report. It is hard to reach with naked eye inspection.
Our instrument outputs full professional data like CIE Lab, LCh, XYZ and accurate ΔE value. It meets international quality audit and brand standard demand.

Products & Materials We Can Test

1. Test color deviation for color masterbatch pellets and base plastic raw granules.

2. Cover all mainstream engineering plastics: PP, ABS, PE, PC and more material types.

3. Inspect finished injection molded housings, accessory parts and end plastic goods.

4. Deliver stable color QC for extruded plastic films, profiles and sheet products.

5. Ensure uniform output for custom colored compounds and modified plastic formulas

Accurate Color Difference Control Range

San’yuan’se professional spectrophotometer can control total color difference ΔE ≤ 0.005(high precision model).
Therefore, for standard industrial mass production, our device maintains ultra-stable testing accuracy and keeps ΔE within 0.005 to 0.01, an error range that is far beyond the resolution limit of the human eye.You can clearly judge qualified / unqualified products with digital data, not feeling.
