For an accurate custom silicone sleeve quote, buyers should include product drawings or samples, sleeve dimensions, material and hardness specifications, logo and surface finishing specifications, desired order quantity, packaging specifications, desired market, compliance specifications, and the desired timeline. The better the information about the project, the more accurate the quotation will be.
The right silicone sleeve custom quote should not be a simple unit price quotation, it should consider the actual product design, material requirements, mold requirements, surface treatment, order quantity, packaging plans, product quality requirements and production feasibility. Many buyers think that just a picture or product name will suffice for a supplier to quote accurately; however, the opposite is true for custom silicone sleeves, as the revisions, pricing or sampling procedure may last for a few days, or even more. Drawings, samples or accurate measurements are most important since sleeve fit, wall thickness, stretch and mold complexity directly affect cost and feasibility.
Quick RFQ Checklist for a Custom Silicone Sleeve Quote
Creating a detailed RFQ beforehand can help you get realistic pricing and avoid unnecessary delays when you are calling in to any custom silicone sleeve manufacturer. Not all the details will be determined in the beginning, but communicating what you have will let the engineering team immediately analyze the feasibility and suitability of the mold, material consumption, manufacturing process, MOQ, and lead time.
When asking for a custom silicone sleeve quote, it’s beneficial to supply drawings, samples, expected volume, material specifications, logo information and packaging specifications early on in the project.
