Detailed Application Scenarios

Handicraft Figurine Printing

HY-901 economy grade pad printing silicone is widely used for logo, pattern and text printing on resin figurines, plaster crafts, ceramic crafts, wooden crafts, glass crafts and metal crafts. Most handicraft products have flat or slightly curved printing surfaces where the 23A general hardness of HY-901 performs well. Handicraft printing typically involves small batch sizes with many product varieties and frequent changes, and HY-901 offers affordable pricing with low pad head production costs suitable for this production model. The 100:2 mixing ratio is simple to operate, and room temperature curing in 2-4 hours enables same day production and use.

Advertising Gift Logo Printing

In the advertising gift industry, HY-901 is used for logo and promotional message printing on thermos cups, notebook covers, pen barrels, keychains, USB drive housings and various gift items. Gift orders typically have small quantities but high requirements for logo printing clarity and accuracy, as the logo represents the customer brand identity. Most gift printing surfaces are flat or slightly curved, and HY-901 general hardness adapts well to these products. Pad heads made from HY-901 provide stable ink transfer, producing logos with sharp edges, clear lines and uniform colors without blurring or missing print issues.

Application and Operation Instructions

Step 1: Preparation

Prepare HY-901 Part A and Part B, digital scale (0.1g precision), stirring rod, vacuum degassing chamber, pad head mold, release agent, nitrile gloves. Clean mold thoroughly, apply thin release agent layer, dry 10 minutes.

Step 2: Weighing

Stir Part A and Part B separately. Weigh accurately at 100:2 ratio (e.g. 100g Part A + 2g Part B). Use precision scale, ratio error within ±0.1g.

Step 3: Stirring

Stir thoroughly for 3-5 minutes, scraping bottom and side walls to ensure uniform mixing. Stir gently to avoid excessive bubbles. Mixed silicone should have uniform color without streaks.

Step 4: Vacuum Degassing

Degas at -0.09MPa for 5-8 minutes until no more bubbles rise. Critical step for pad head quality, insufficient degassing causes pores and printing defects.

Step 5: Mold Pouring

Pour slowly along mold side wall, let silicone flow naturally. Fill slightly above mold level to compensate for curing shrinkage.

Step 6: Curing and Demolding

Cure at room temperature 25°C for 2-4 hours. Confirm full curing by finger press test. Demold carefully from edge. Rest 24 hours before use for optimal performance.

FAQ

Q1: What is the difference between HY-901 economy grade and other models?

A1: HY-901 is the economy general purpose model with 23A hardness and the most affordable price, suitable for flat or slightly curved surface general printing in small and medium batch production. For flat signs, buttons, packaging boxes and regular gift items, HY-901 is fully sufficient with the highest cost performance. For multi color overprinting choose HY-912, for high volume automated lines choose HY-902, for large curvature irregular curved surfaces choose HY-916.

Q2: Is HY-901 reliable for daily production?

A2: Yes, HY-901 provides stable and consistent performance for daily general purpose printing. With tensile strength ≥3.0MPa, tear strength ≥12kN/m and elongation ≥300%, pad heads made from HY-901 achieve 50,000 to 80,000 prints under normal conditions. Every batch is tested before shipment with COA reports provided, ensuring consistent quality. The affordable price makes it very cost effective for small and medium batch production.

Q3: Why does the silicone not cure or remain sticky after curing?

A3: Incomplete curing or sticky surfaces usually have several causes: inaccurate Part B ratio, always weigh accurately at 100:2. Uneven mixing especially at container bottom and walls, always scrape and stir thoroughly for 3-5 minutes. Contact with curing inhibiting substances such as tin, sulfur or amine containing materials, ensure clean tools and containers. Expired or improperly stored Part B curing agent, store sealed and use within shelf life. Check these causes one by one, or contact technical support for assistance.
