Detailed Application Scenarios
Craft Industry Application
HY-912 multi color universal pad printing silicone is widely used in the craft industry, mainly for multi color pattern and logo printing on resin crafts, ceramic crafts, glass crafts, metal crafts, wooden crafts and other craft products. Crafts usually have fine patterns with rich colors, requiring multi color overprinting, which demands high resilience and overprint accuracy from pad heads.
Pad heads made from HY-912 offer excellent resilience, quickly recovering their original shape during multi color overprinting, ensuring precise alignment for every color layer without misalignment or ghosting. Meanwhile, this model provides uniform ink transfer with clean pickup and thorough release, producing full color patterns with clear edges, meeting the high appearance quality requirements of the craft industry. With hardness 25 Shore A and balanced softness and firmness, it ensures stable printing pressure while conforming well to slightly curved and irregular surfaces of crafts, making it the ideal choice for multi color printing in the craft industry.
Gift Industry Application
In the gift industry, HY-912 is used for multi color overprinting of logos and patterns on advertising gifts, promotional gifts, business gifts, holiday gifts and other gift products. Gifts usually require printing customer brand logos and promotional patterns with high printing quality and overprint accuracy, while gift orders are usually in large batches requiring stable and durable pad heads.
The high overprint accuracy of HY-912 ensures clear and accurate brand logos on gifts with well defined multi color patterns, enhancing the overall quality of the gifts. This model with tensile strength ≥3.5MPa and tear strength ≥15kN/m has excellent physical properties, making pad heads resistant to cracking or damage with long service life, withstanding high volume printing. For flat or slightly curved products commonly seen in the gift industry, pad heads made from HY-912 provide stable and uniform printing results, making it a reliable choice for gift printing.
Application and Operation Instructions
Step 1: Preparation
Prepare HY-912 Part A (silicone) and Part B (curing agent), digital scale, stirring rod, vacuum degassing machine, pad head mold, mold release agent, gloves and other tools. Ensure the mold is clean and dry, apply a thin uniform layer of mold release agent inside the mold and let it dry.
Step 2: Weighing and Mixing
Accurately weigh Part A and Part B by weight ratio 100:2. For example, take 100g Part A and add 2g Part B. Use a digital scale for precise weighing with error within ±0.1g. Inaccurate ratio will affect curing results and pad head performance.
Step 3: Stirring
Stir Part A and Part B thoroughly for 3-5 minutes. Scrape the bottom and side walls of the container to ensure uniform mixing without streaks. Stir gently to avoid introducing too many bubbles. The mixed silicone should have uniform color without obvious color difference.
Step 4: Vacuum Degassing
Place the mixed silicone in a vacuum degassing machine and degas for 5-8 minutes at -0.09MPa negative pressure until no more bubbles rise to the surface. Degassing is a critical step to ensure pad head quality. Insufficient degassing causes internal pores in pad heads, affecting printing results and service life.
Step 5: Mold Pouring
Slowly pour the degassed silicone into the prepared pad head mold. Pour from one side of the mold and let the silicone flow naturally to avoid creating new bubbles. Fill slightly above the mold level as silicone will shrink slightly during curing.
Step 6: Curing and Demolding
Cure at room temperature (25°C) for 2-4 hours. Once fully cured, demold carefully. Avoid excessive pulling that may cause deformation or tearing. It is recommended to let the demolded pad head rest for 24 hours before use to achieve optimal performance.

Precautions
It is recommended to wear nitrile gloves during operation to avoid direct skin contact with uncured silicone and curing agent. Avoid contact with substances containing tin, sulfur, amines and similar materials as these may inhibit silicone curing. Part A and Part B should be stirred separately before use. Weighing must be accurate as excessive ratio deviation affects curing results. Mixing must be uniform otherwise local incomplete curing may occur. Recommended curing temperature between 15-35°C, lower temperatures extend curing time. Maintain ventilation in the operating area and avoid inhaling volatile gases.
Storage
Store products in a cool and dry place at storage temperature 5-30°C, avoid direct sunlight and high temperature environments. Shelf life 12 months unopened, use as soon as possible after opening. Reseal immediately after each use to prevent curing agent from contacting moisture in air. Part B (curing agent) is moisture sensitive and must be stored sealed. Refrigerated storage can extend shelf life, but allow to return to room temperature before use.
FAQ
Q1: How many colors can HY-912 handle for overprinting?
A1: HY-912 multi color universal grade is designed for multi color overprinting with excellent resilience and high overprint accuracy, suitable for 2 to 6 color overprinting. For more complex overprinting with additional colors, it is recommended to conduct small batch testing first to confirm overprint accuracy meets requirements before mass production. The high resilience of this model ensures pad heads quickly recover after repeated pressing, reducing overprint errors.
Q2: What causes misalignment during multi color overprinting?
A2: Common causes of misalignment in multi color overprinting include: insufficient pad head resilience causing slow recovery after deformation; pad head hardness too soft or too hard causing unstable printing pressure; inaccurate printing machine positioning; insecure substrate fixation. It is recommended to select high resilience models such as HY-912, check whether pad head hardness matches, and confirm printing machine positioning and substrate fixation conditions.
