DBM is a custom EPP foam molding manufacturer in China, also molding EPS and composite foams. Lightweight EPP, EPS, and foam composite parts — mostly air, engineered to carry load, absorb impact, and insulate. Send us your part and we take it from there: material selection, structural design, sampling, and volume production. Recyclable, low-carbon, ISO 9001 certified.

02Materials · EPP

EPP — repeat-impact
& reusable.

Expanded Polypropylene — a high-performance closed-cell foam known for impact absorption, compression recovery, chemical resistance, thermal insulation, and repeated-use durability. For reusable packaging, drones, battery protection, automotive parts, and returnable trays.

02Materials · EPS

EPS — cost-efficient
& insulating.

Expanded Polystyrene — a lightweight foam widely used for protective packaging, thermal insulation, disposable shipping, and shaped cushioning. Selected when the project needs low weight, good insulation, efficient production, and competitive cost.

02Materials · Composite

Foam that carries
more functions.

When foam alone is not enough, DBM integrates reinforcement parts, carbon fiber rods, plastic inserts, embedded components, and secondary-processing features — so the part provides not only cushioning, but strength, positioning, connection, mounting, and assembly functions.

03Beyond EPP & EPS

Three more foams,
when the job asks for them.

Beyond EPP and EPS, DBM also molds these three: for firmer support at very low weight, for parts that must flex and stay dry, or for parts that hug a curved surface and keep coming back. Each page carries the full property table and a selection guide.

M.03Best for

Firm support at very low weight

EPO16–33 g/L · 120–190 kPa @25%

PS/polyolefin composite bead foam — rigid-feeling, still impact-safe, low thermal conductivity. →

M.04Best for

Flexible, water-resistant, reusable parts

Beaded EPE20–74 g/L · 7 densities

Bead-molded polyethylene — the widest density span, low compression set, <5% water absorption. →

M.05Best for

Soft contact surfaces & sealing

EVA30–50 g/L · 205–243% elongation

Cross-linked closed-cell EVA — soft, conformable, the highest elongation at break of our production foams, recovers to within 2%, <1% water absorption. →

03Applications

Foam solutions for multiple industries.

Whatever you build — drones, batteries, appliances, precision parts — we design the foam around how your product is actually shaped, loaded, handled, and shipped. You describe the job; we deliver the part that does it.

Reusable Industrial Packaging

Engineered EPP trays and dunnage that replace single-use packaging. Reusable, recyclable, designed around real handling cycles.

06Circular Use

Built to last, kept in use.

Sustainability targets are yours to hit — we help you get there. Parts designed for years of reuse instead of single trips cut your packaging spend and your waste stream at the same time, and recover back into the material loop when retired.

Reuse

Used again, not once

Repeat-impact EPP trays and dunnage return to service across many handling cycles, replacing single-use packaging.

Longevity

A long service life

Repeat-impact durability and a wide temperature range keep parts performing for years, not a single trip.

Recovery

Recover, not landfill

Single-material EPP and EPS can be reclaimed back into the bead stream; recycled-content grades are supported.

Less material

Lighter footprint

Bead foam is mostly air — less material per part and lower weight reduce transport energy and emissions.
