Bottle cap molds for food packaging

Bottle cap molds play a vital role in the food packaging industry. These molds are designed to produce caps in different shapes, sizes, and materials, ensuring compatibility with various types of bottles and cans. In this article, we’ll provide an overview of the common types of bottle caps used in food packaging and some related professional knowledge.

Commonly used bottle cap molds in the food packaging industry include those for screw caps, snap-on caps, flip-top caps, and tamper-evident caps. Screw caps are widely used in beverage packaging, while snap-on caps are common in the dairy industry. Flip-top caps are popular in condiment packaging, and tamper-evident caps are essential for ensuring product safety.

When it comes to the materials used in bottle cap molds, aluminum and steel are the most common. Aluminum molds are lightweight and have high thermal conductivity, making them suitable for producing high-quality caps at a faster rate. On the other hand, steel molds are more durable and have a longer lifespan than aluminum molds. Steel molds can withstand high temperatures and pressures, making them ideal for mass production of bottle caps.

Mold description

  1. Mold Materials We use high-quality materials such as 203, P20H, and 71H for the main components of the molds, including the mold plate and related parts. In addition, we also use high-quality cushion materials such as 2083, 234, 231, 23162738, and S136. Professional heat treatment is applied to the main parts of the bottle cap molds to ensure that the material hardness exceeds HRC45.

  2. Mold Design We draw inspiration from Western bottle cap mold designs and combine them with our rich experience to create innovative molds that produce perfect bottle caps.

  3. Mold Part Processing We use high-speed CNC machining centers to process the molds with standardized operations, ensuring the precision and interchangeability of every mold part.

  4. Fast Cycle Time By applying a perfect cooling waterway and using fast-cooling materials, we optimize the cycle time of the bottle cap molds and achieve stable, fast production, resulting in improved production efficiency.

  5. Number of Cavity Selection We offer a range of cavity options to choose from, including 1 cavity, 1×2 cavities, 2×2 cavities, 2×3 cavities, 2×4 cavities, 2×6 cavities, 3x cavities, 3×8 cavities, 4x cavities, 4×6 cavities, 4×8 cavities, 6×6 cavities, 6×8 cavities, and 6×12 cavities.

  6. Hot Runner System Our bottle cap molds feature a self-developed, high-quality hot runner system that can withstand ultra-high injection pressures without leakage. After optimizing the mold gate, the molds can produce perfect molded products. All parts of the hot runner system are made of high-precision, high-toughness, and wear-resistant materials.

  7. Mold Delivery Time We offer fast delivery times, with a typical delivery time of no more than 60 working days for bottle cap molds.

By using high-quality materials, innovative design, and standardized operations, we can produce bottle cap molds that meet our customers’ requirements for household packaging.
