Rapid Prototyping Grade – B – Precision Instrument Packaging Box

Product introduction

The B-rapid prototyping grade is a versatile expanded polystyrene packaging material widely used for electrical appliances, ceramic goods, fishing boxes, fruit and vegetable crates, floats, and even small crafts or general packaging. HUASHENG B-grade EPS packaging foam material works smoothly with both automatic forming machines and electric-drive molding setups, where production speed is usually higher. Thanks to its stable EPS foam molding performance, the B-grade expanded polystyrene packaging material delivers consistent results—whether you’re running bulk orders of moulded polystyrene packaging or just making a batch of custom EPS packaging foam parts.

Product characteristics

• Uniform bead size with smooth flow, making EPSfoam molding more stable.
• Short curing time, speeding up production cycles.
• Fast demoulding on automatic forming machines, with higher vacuum cooling efficiency.
• Strong bead fusion, giving moulded polystyrene packaging high impact resistance.
• Recommended foaming rate: 40–65 times for reliable expanded polystyrene packaging material.

Product Advantages

• Strong protection: fragile productslike ceramic lamps or glass vases don’t crack that easily with HUASHENG B-grade EPS packaging foam material.
• Saves on freight: HUASHENG B-grade EPSpackaging foam material is extra light, which can help you save on your transport spending.
• Works across setups: whether you’re making small moulded polystyrene packaging inserts or big expanded polystyrene panels, the beads flow steadilyand don’t clog up machines.
• Keeps its shape: the B-grade EPSpackaging foam doesn’t sag or warp after sitting in a warehouse for months.
• Less waste: compared with denser foams, you don’t end up with piles of useless offcuts. Production lines stay cleaner, and it’s just less hassle to deal with.

Application Fields

• Electrical packaging: suitable for expanded polystyrene packaging material used in appliances and related products.
• Ceramic packaging: works well with moulded polystyrene packaging for delicate items.
• Fishing and fruit boxes: commonly made with EPS packaging foam, light yet strong.
• Vegetable boxes and floats: made through efficient EPSfoam molding processes.
• Handicrafts and general packaging: adaptable to custom EPSfoam packaging designs.
• Compatible with automatic forming machines and electric drive forming machines, with higher efficiency in expanded polystyrene molding.
