Color reference
Share an approved plaque, pellet, chip, swatch, sample, or recognized color-card reference.
Core capability / reference-led color matching
Custom color masterbatch built around your resin and process.
Custom color is not only a shade selection. The same target color can behave differently across resins, processing routes, part designs, and end uses. Sinfone starts with the buyer's real reference and production conditions so the discussion is tied to the final application.
Why the project inputs matter
A custom formula begins with the application, not a public color list.
Sinfone does not present every custom formula as a standard SKU because the useful answer depends on the material system and production conditions. These inputs help turn a color request into a reviewable project.
Base resin
Identify the resin or material direction so compatibility can be considered from the beginning.
Process and end use
Explain how the part is processed and where it will be used, including any known appearance requirement.
Practical project brief
What to include in a useful first inquiry.
You do not need a finished technical specification to contact us. Share what you already know, and mark anything that still needs discussion.
Target color
Physical reference, approved sample, color-card reference, or a clear explanation of the target.
Material
Base resin, resin grade if known, and any compatibility concern already identified.
Processing route
Injection molding, blown film, blow molding, extrusion, or another relevant method.
End application
Final part, housing, film, package, cable, consumer product, or other intended use.
Project requirements
Known tolerance, loading expectation, testing request, document need, or approval method.
How a discussion begins
A clear path from reference to sample review.
Commercial terms, timing, and final product structure are confirmed only after the project inputs are reviewed.
1. Review the inputs
We begin with the color reference, resin, process, end use, and the requirements the buyer already knows.
2. Discuss the sample path
After the initial fit review, we can discuss the most practical way to move into sample evaluation.
3. Confirm the next step
Relevant testing, documents, commercial details, and production follow-up are handled for the specific project.
Custom color questions
The essentials, answered directly.
Why do you not publish a fixed catalog of every custom color?
Custom color performance depends on the resin, processing method, end application, physical reference, and required appearance. We therefore review most custom color projects individually instead of presenting every formula as a standard public SKU.
What color references can I send?
An approved plaque, pellet, chip, swatch, physical sample, or recognized color-card reference can provide a useful starting point. A physical approval reference is especially helpful when final appearance matters.
Which resin and processing information is useful?
Please share the base resin or resin grade if known and explain whether the product is injection molded, blown, extruded, calendered, or processed another way. Final fit is reviewed project by project.
Can you discuss samples and supporting documents?
Samples and relevant supporting documents can be discussed after the resin, process, color target, application, and project requirements are reviewed.
Do I need to know every technical requirement before contacting you?
No. Send the information you already have and identify what still needs discussion. A clear color reference, resin direction, process, and end use are the most useful first inputs.
Have a physical reference or a new color project?
Send the target resin, processing method, end use, color reference, and any known tolerance, testing, or documentation requirement. We will use those details to review the most practical next step.
