Why Automate Your RTV Tube Packaging?
If you are still filling and sealing RTV tubes manually or with semi-automated equipment, you already know the pain points: inconsistent fill volumes, weak seals that lead to product spoilage, slow output that bottlenecks your entire production line, and the constant headache of labor turnover.
This machine changes all of that.
Designed specifically for RTV silicone sealants and other high-viscosity materials, our fully automatic tube filling and sealing machine takes the guesswork and heavy lifting out of your packaging process. It handles everything – from feeding empty tubes to delivering finished, neatly sealed products – with minimal human intervention and maximum reliability.
What Makes This Machine Different?
We are not going to overwhelm you with technical jargon. Instead, let us walk you through what this machine actually does, step by step, and why each step matters to your business.
Step One – It Feeds Itself, So You Do Not Have To
Loading tubes one by one is tedious and time-consuming. This machine uses an automatic feeding system that takes tubes from a bulk hopper and positions them perfectly for the next stage. A downward pressure mechanism ensures every tube sits securely, while an automatic direction correction feature rotates each tube into the right orientation – no manual sorting, no misaligned tubes, no wasted time.
Why this matters to you: Less manual handling means lower labor costs, fewer errors, and a smoother production flow.
Step Two – It Fills with Precision, Not Guesswork
RTV sealants are thick, sticky, and expensive. Overfill a tube and you are giving away profit. Underfill it and your customer receives a product that feels short-changed.
Our high-viscosity filling system delivers accuracy within ±1%. Whether you are running 20 tubes per minute or 40, each tube receives exactly the amount it should – no more, no less.
Why this matters to you: You save material costs, maintain product consistency, and protect your brand reputation.
Step Three – It Seals in Two Stages, for a Seal You Can Trust
This is where many machines fall short. A weak seal on an RTV tube is not just a cosmetic issue – it is a functional disaster. RTV silicones cure when exposed to moisture in the air. If the seal is not completely airtight, the product begins to cure inside the tube, ruining it before it even reaches the customer.
That is why our machine uses a dual heating approach:
Internal heating blows hot air inside the tube opening to soften the inner wall. This prepares the material for a smooth, even fusion without damaging the outside of the tube or any printed graphics.
External heating clamps the tube tail from the outside and applies heat and pressure to fuse the seal completely.
Together, these two heating steps create a hermetic, moisture-proof seal that keeps your RTV product fresh and usable for its full shelf life.
Why this matters to you: Your customers receive a product that performs as expected. No returns due to premature curing. No complaints about hardened sealant.
Step Four – It Trims the Tail for a Clean, Professional Finish
After sealing, a small amount of excess material may remain at the tail end. Our automatic tail trimming system cuts this away cleanly, leaving a smooth, neat edge.
Why this matters to you: Your tubes look professional on the shelf. A clean finish signals quality to your customers and reinforces trust in your brand.
Step Five – It Sends Finished Tubes Out, Ready for Packaging
Once trimmed, finished tubes are carried by the automatic output system to a collection point, ready for boxing, cartoning, or further packaging – all without any manual transfer.
Why this matters to you: Your production line keeps running smoothly, with no bottlenecks at the end of the machine.
