What is Cold Pressing?

In the production of pickleball paddles, cold pressing is a critical process primarily used for bonding composite materials (such as fiberglass or carbon fiber) with core materials (like polypropylene honeycomb or aluminum honeycomb)

1,Low-Temperature Curing

Unlike hot pressing (high-temperature, high-pressure curing), cold pressing is typically performed at room temperature or slightly elevated temperatures (usually below 50°C). It relies on prolonged pressure to allow adhesives or resins to cure naturally, avoiding damage to material properties caused by high heat.

Ideal for temperature-sensitive materials (e.g., certain polymer cores), reducing risks of warping or delamination.

2,Pressure Control

Hydraulic or mechanical presses apply uniform high pressure to composite layers and the core, ensuring tight bonding, eliminating air bubbles or gaps, and enhancing the paddle’s stability and durability.

3,Preserving Material Integrity

Cold pressing prevents fiber brittleness or core collapse due to high temperatures, maintaining the material’s original strength and shock absorption.

Why Use Cold Pressing for Pickleball Paddles?

*Surface Smoothness: Ensures tight adhesion between fiber surfaces (e.g., fiberglass) and the core, minimizing warping for better ball control.

*Weight Management: Prevents excessive resin seepage into the core, avoiding unnecessary weight gain.

*Eco-Friendly & Energy-Efficient: No heating equipment required, reducing energy consumption.

Cold Pressing vs. Hot Pressing

Cold Pressing	Hot Pressing
Low-temperature, slow curing (24–48 hrs)	High-temperature, fast curing (hours)
Best for fine composites	Best for dense materials (e.g., carbon fiber)
Higher flexibility in final product	Higher rigidity in final product
Lower cost	Higher equipment costs

Practical Application

“cold-pressed fiberglass surface”, meaning the face is bonded to the polypropylene honeycomb core via cold pressing. This balances lightweight design (210g) and durability (TPU edge guard + 10mm thickness), making it ideal for beginners or casual players.
