ABC Wear-Resistant Rotary Die Head

Blow Moulding Machine Heads Three-layer for extrusion die head blow moulding machine head film blowing machine, head can be customised

Specific Applications
1. Multi-layer packaging film production — combines three material layers into a single film wall, suited for products that need a layered structure rather than a single-material film
2. Courier bag manufacturing — produces the film used for express delivery mailer bags
3. Aquatic bag production — makes film for bags used to pack and transport seafood or aquatic products
4. Rubbish bag / trash bag film — supports the film gauge and strength needed for waste bags
5. Multi-material processing lines — works with HDPE, LDPE, LLDPE, PE, PETG, and HIPS, so it fits plants running more than one resin type across different orders
6. Recycled material blending — recycled material can be fed into the process without swapping the die head, useful for plants mixing virgin and recycled resin

Purchasing Motivation

Buyers looking at a ABC Wear-Resistant Rotary Die Head are usually trying to solve a specific problem: uneven film thickness that keeps showing up in the same position, run after run, because the die head doesn't move. A fixed die head can produce good film, but any small imperfection in the runner tends to leave a repeating mark. Switching to a rotary design spreads that variation around the full circumference instead of concentrating it in one spot.

This ABC Wear-Resistant Rotary Die Head also handles three-layer co-extrusion, which is relevant for buyers producing multi-layer packaging film rather than single-material bags — it lets a plant combine three different resin layers through one die head instead of running separate single-layer setups. The size range from 30mm to 1000mm covers a wide span of blown film machine models, and the 40Cr forged construction with chrome-plated runners is built to hold up under the added wear that comes with continuous rotation. 

Solving Customer Pain Points

Plants running multi-layer film often deal with a few specific issues that a fixed, single-feed die head doesn't solve well:

1. Repeating thickness variation: because a fixed die stays still, any small unevenness in the runner or heating shows up in the same spot on the film roll every time, appearing as visible banding. The rotating design on this ABC Wear-Resistant Rotary Die Head solves this by distributing that inconsistency around the full circumference of the film tube instead of letting it concentrate in one spot.

2. Layer control across three materials: managing three separate material layers through one head risks one layer overwhelming the others or causing weak bonding between layers. The three-layer structure here is built into the die body itself, so the three materials are combined in a controlled way as part of the die's design, rather than being bolted together from separate single-layer heads.

3. Limited visibility into running conditions: it's hard to tell whether a die head is actually running within its normal operating range during long production runs. This ABC Wear-Resistant Rotary Die Head comes with a pressure gauge and current meter mounted directly on it, giving operators a quick way to check running conditions without needing to inspect the extruder separately.
