Control System Upgrades

Retrofit. Don't Replace.

Long mechanical life.Short electronic half-life.

Your extruders, dies, blenders and conveying will run for decades. The controls on them will not — support ends, spares disappear, interfaces fall behind. In a twenty-year-old line, the bottleneck is almost never the steel. It's the brains.

The Obsolescence Check

Four things we see on plant floors every week. If any of them describes your line, an upgrade is worth a conversation — the cost of unplanned downtime far outweighs the cost of upgrading.

20+ Years Old

A Controller From Another Era

Slow by today's standards, and it will eventually fail. On the oldest generations, spare parts are no longer available at all.

10+ Years Old

Boards Nearing End Of Support

The same trajectory, a decade behind. Support windows close long before the mechanics wear out.

No Weight Control

Volumetric Or Manual Mixing

You're working to set speeds, not absolute weights. Blend drifts whenever material changes.

Weighing Only

Non-Controlling Gravimetrics

Measuring but not correcting — no machine-direction or cross-direction control on the line.

Find Your Starting Point

Where you are today decides what an upgrade looks like — and how quickly it pays back.

Path One

You Already Have Gravimetrics

Your blender has years left in it. Your controller does not.

The upgrade reuses all existing mechanics and extends service life by up to ten years. No re-piping, no re-training. Nexus mounts to the frame you already have and swaps without tools — minutes, not days. Production continues.

Path Two

You're On Another Brand's Frame

It fits the frame you already own — including frames that aren't ours.

The Nexus controller is backward-compatible and mounts onto existing gravimetric frames. Standard comms throughout: Modbus, Profinet and Ethernet/IP to your extruder PLCs and ERP.

Path Three

You're Still Volumetric

Set speeds move your blend ratio. Absolute weights don't.

When material density or particle shape changes, a volumetric blend changes with it. Gravimetric control holds ±0.01% mixing accuracy run to run, and machine-direction control keeps product on spec instead of giving material away.

TSM control retrofitted onto existing blender frames

Current-generation TSM control, mounted on frames the customer already owned.

Control module lifted off an existing blender frame by hand

The module swaps by hand. Minutes, not days.

What You Keep

The blender, hoppers, augers and frame — all existing mechanics stay in place.

Your piping layout. No re-piping and no line rebuild.

Your operators' working knowledge. No re-training programme.

Your production schedule. The module swaps in minutes, not days.

What Changes

Current-generation control hardware, with spares and support available.

Up to ten more years of service life from equipment you already own.

True gravimetric correction — weighing and acting, not just weighing.

Line data you can actually use, on standard comms to your PLCs and ERP.

What An Upgrade Delivers

±0.01%
Mixing accuracy, held run to run
+10 yr
Service life added to existing equipment
3%
Average yield increase across installations
20%
Average labor reduction on upgraded lines
One Platform, Every Process

Wherever material is dosed, blended or conveyed, the same upgrade logic applies. This is not a single-process offer.

Blown Film
Cast Extrusion
Sheet Extrusion
Pipe & Profile Extrusion
Compounding & Recycling
Wire & Cable Extrusion
Injection Molding

What Processors Tell Us Afterwards

Different plants, different processes, the same three outcomes.

The Line Kept Running

Control upgraded on existing mechanics, with production continuing through the changeover rather than stopping for a rebuild.

The Blend Stopped Drifting

Consistent ratios across changing material streams and batch sizes, with give-away brought back under control.

The Data Became Usable

Consumption and yield reported line by line, feeding straight into the plant systems already in place.

Named case studies available on request.

Never Stranded

TSM designs and manufactures its own control hardware and writes its own software. An upgrade from us never depends on another company's discontinued platform.

Our Own Hardware

Designed and built by TSM, not sourced from a third-party controls vendor.

Our Own Software

Written in house, so the roadmap is ours to keep supporting.

Support That Continues

Parts and software support continue for years after install. Equipment running in 78 countries.

Download The Retrofit & Upgrade Brochures

Both documents arrive by email: the retrofit and upgrade options for gravimetric dosing, blending, conveying and control — on the lines you already run, TSM-built or not.

Retrofit — Blown Film: gravimetrics plus bubble and profile control — automatic air ring, IBC, CD gauge and width control, OptiCool and GPA EVO II measurement.

Upgrade — General: the TSM Nexus controller upgrade, and the full dosing, conveying, storage and integration scope on any gravimetric line.

Both set out why ageing controls — not the mechanics — are the real risk, with installed examples at Polystar and Polykemi.
