Product Introduction

When producing sponge linings for electric vehicle helmets, manual bonding and cutting is relatively inefficient, often resulting in poor adhesion and rough edges. Sports helmet breathable sponge linings require precise hot pressing, but traditional equipment cannot adapt to pressure needs of different sponge thicknesses. This Fully Automatic Sponge Helmet Lining Hot Press integrates automatic feeding, hot pressing, and cutting with a precision temperature-controlled die head. It helps improve production efficiency for helmet factories and optimize the fitting accuracy of sports helmet linings, meeting mass production needs of helmet linings.

Product Features

Integrated automatic process: Sponge roll feeding, hot pressing, and edge cutting are completed synchronously without manual step-by-step operation. With proficient operation and stable material supply, production efficiency can be significantly improved, though actual efficiency may vary based on operator proficiency and material consistency.

Precision temperature-controlled die head: Temperature stabilizes within the 120-160℃ range, with hot pressing time error kept to a minimum. Adhesion strength between sponge and EPS foam remains stable, meeting mainstream helmet safety testing standards.

Sponge thickness adaptive adjustment: Automatically adapts pressure for 3-15mm thick sponges, reducing damage to thin sponges and ensuring firm bonding for thick ones, with stable product yield.

Automatic discharge and sorting: Formed linings are automatically discharged and sorted into qualified/defective products, eliminating manual sorting and saving post-processing time.

Application Scenarios

Electric Vehicle Helmet Lining Production Scenario: Helmet factories need to mass-produce 400×600mm EPS+sponge linings. Manual bonding and cutting is relatively inefficient, and the machine's integrated automatic process can significantly increase output scale. The adhesion strength remains stable, generally meeting GB2811 helmet safety testing requirements, and adapting to peak season order demands.

Sports Helmet Lining Forming Scenario: Cycling helmets require precise hot pressing of 10mm thick breathable sponge linings. Traditional equipment cannot adapt to pressure needs of sponge ventilation holes. The machine's adaptive pressure adjustment avoids ventilation hole areas, and ventilation hole patency remains stable after hot pressing. The lining fitting accuracy is controlled within a reasonable range, helping improve wearing comfort and safety of sports helmets.

FAQ

1.Q: Can the machine complete both hot pressing and edge cutting of sponge linings simultaneously?

A: The integrated process supports synchronous feeding, hot pressing, and cutting, eliminating additional cutting steps. Edge cutting accuracy remains stable with no obvious burrs, directly suitable for helmet assembly.

2.Q: Will 15mm thick high-density sponges be damaged or poorly bonded during hot pressing?

A: The sponge thickness adaptive system automatically adjusts pressure based on sponge density. After hot pressing, 15mm thick sponges have stable adhesion strength, reducing the risk of damage and deformation, meeting mainstream helmet safety standards.

3.Q: Will hot-pressed sponge linings delaminate in high and low-temperature environments?

A: The precision temperature-controlled die head uses molecular-level thermal bonding technology. Linings exhibit stable weather resistance in -40℃~80℃ environments, generally meeting helmet weather resistance requirements.

4.Q: How long does it take to adjust the machine when changing molds for different helmet lining sizes?

A: The quick-release mold design allows for convenient mold changes after familiarization, without professional tools, adapting to multi-specification helmet lining production.

5.Q: What types of defective products can the automatic discharge and sorting system identify?

A: The system uses visual inspection to detect common defects such as poor adhesion, rough edges, and sponge damage. Sorting accuracy remains stable, reducing manual re-inspection costs.

6.Q: Will hot pressing temperature stability decrease after 12 hours of continuous operation?

A: The closed-loop temperature control system + water cooling keeps die head temperature fluctuation within a reasonable range, maintaining relative stability during continuous operation and helping ensure mass production consistency.

7.Q: Can the machine handle sponge linings with adhesive backing?

A: Supports hot pressing of adhesive-backed sponges. The temperature control system precisely activates adhesive temperature, and after proficient operation, it can avoid adhesive overflow or failure, with stable adhesive adhesion after bonding.
