PEPHAWK crafts superior custom t-shirt patches using advanced high-frequency technology. Discover our precision process for quality, durability & design.

1. Foundation: Premium Materials & Initial Preparation

The journey to an exceptional custom t-shirt patch begins with meticulous groundwork:

• Strategic Material Sourcing: Our process, as exemplified by protocol JY2309AA001, begins with the careful procurement of premium materials, such as top-layer coffee-colored leather. These selected materials are then systematically transferred to our specialized printing department.

• Expert Initial Printing: Before the high-frequency stage, essential printing processes are carried out. This may include the application of specific coatings like transparent gold oil (e.g., applied in 3-3 sequences or layers, indicating a precise application method) to enhance the material or prepare it for subsequent steps.

• Transfer to High-Frequency Processing: Once initial preparations are complete, the materials are handed over for the critical high-frequency heat pressing phase.

2. The Core: Precision High-Frequency (HF) Welding & Pressing

High-frequency technology is central to creating robust and intricately bonded custom t-shirt patches. PEPHAWK adheres to strict operational guidelines:

• Pressure Application Tailored to Material:

  • For leather components, hydraulic pressure is typically employed within the HF machinery.

  • For fiber and silicone elements, pneumatic (air) pressure is the preferred method. This differentiation ensures optimal bonding and material integrity.

• Critical Temperature Control:

  • The specific materials noted are processed using HF welding at a carefully controlled temperature range of 70-80°C.

  • Temperatures below this range can result in an insufficient or weak bond, diminishing the pressing effect. Conversely, temperatures exceeding this range risk scorching the material, causing it to become糊 (mushy/burnt) or curl, compromising the quality of your custom t-shirt patches.

• Fine-Tuning Machine Adjustments for Perfection:

  • Mold Balance: Side-mounted knobs on our HF equipment allow for precise adjustment of mold balance, ensuring even pressure distribution.

  • Pressing Angle & Depth: Top-mounted knobs control the pressing angle, which in turn regulates the depth of the HF weld. A lever mechanism ( lever under the table) can further increase the pressing depth.

  • Avoiding Defects: Our technicians are highly skilled in managing these adjustments, as excessive pressing depth can lead to undesirable peeling or flaking of the material.

• Precision Alignment:

  • Before the HF pressing cycle begins, adhesive paper or specialized jigs are used to accurately align the material components.

  • During the pressing phase, alignment with specific reference marks (e.g., - internal alignment markers) is crucial to ensure every element is perfectly positioned.

3. Post-Pressing: Curing & Specialized Treatments

Following the HF process, further treatments ensure the longevity and finish of your custom t-shirt patches:

• Ink Curing Options:

  • Printed inks can be allowed to air dry naturally, typically over a period of 12-24 hours.

  • Alternatively, a controlled baking process at 60-80°C can be used. Importantly, high-temperature baking is avoided for standard inks to preserve color integrity and material properties.

• Specialized Silicone & Fabric Treatments:

  • For silicone applications involving double-sided transfer paper printing, a specific baking protocol of 130°C for 60 minutes is employed.

  • Silicone printed onto a fabric base is typically cured by baking at 100°C for 60 minutes.
