Inventory Replenishment / Injection Molding

Arda's inventory replenishment software for injection molding and plastics manufacturers

Your ERP plans resin, color and inserts, and it plans them well. Nothing plans the purge compound, desiccant, heater bands and gaylords sitting on the shelf beside the press, and any one of them costs you the same press time as a resin shortage. Arda puts a scannable card on those items, so a scan fires the reorder and the press keeps running.

Your first 10 cards are free. Runs alongside the plastics ERP you already chose, no rip and replace.

Trusted by manufacturers including Fat Fender, Austere, and Assembly Industrial.

Never stock out on anything your plant holds

A stockout is a reorder that fired too late, or never fired at all. Count-based systems leave that trigger to a person, and people are busy. Arda makes the trigger physical: the card on the bin is the reorder, sized to your supplier's lead time, so replenishment starts the moment stock runs low and the shelf refills before the second bin runs dry. That works the same on a pail of purge compound, a box of desiccant, or a pallet of gaylords.

The trigger can't be skipped

Scanning the empty bin is the fastest way to get more, so the reorder fires on its own, every time.

The buffer is sized, not guessed

Reorder point and safety stock are set to your real burn rate and lead time, so the second bin always covers the wait.

It holds as demand shifts

When a job changes what you burn, you resize the card once. Nobody recalculates a min/max by hand.

The shelf did not fail. The signal did.

Your press stops for the one thing that was never on a bill of materials

Molding is more BOM-driven than most shops. Resin, color and inserts are all part numbers, and your ERP plans them properly against your release schedule. But the shelf next to the press holds purge compound, desiccant, heater bands and gaylords, and none of those belong to a part number, so nothing is planning them at all. When one runs out, the press sits exactly as long as it would for a resin shortage.

01

The color change that stops at the purge pail

The tool is hung, the next color is dosed, and the tech reaches for purge compound that is not there. Now it is either a wait or a long push of virgin resin through the barrel, which burns expensive material and drives scrap up while the press makes nothing anyone can sell.

02

Wet resin nobody saw coming

Desiccant beds and dryer filters degrade quietly, so dew point creeps and the resin runs wetter than the sheet says. The first sign is splay two hours into a run, and by then the lot is scrap. No planning run ever asked whether the desiccant had been changed.

03

Good parts that cannot leave the building

The run is perfect and the gaylords are gone. Finished parts stack up beside the press because there is nothing to put them in, the truck leaves light, and a molder does not get paid until the parts ship.

How does inventory replenishment work in a molding plant using Arda?

Arda's inventory replenishment software puts a scannable card on every item a molding plant stocks, starting with the shelf your planning run was never pointed at, so the scan fires the reorder on its own. No stock check, no purchase order to type, no ERP rollout. Scan a card, the material shows up.

Your ERP plans the first row. Nothing plans the second one.

A bill of materials describes a part, so it can only cover what goes into the part. Purge compound belongs to a changeover. Desiccant belongs to a dryer. Gaylords belong to a shipment. None of them belong to a part number, so none of them get planned, and any one of them stops the press. The same card works on both rows, which means you can start on the second one and extend to the first whenever you want.

1

Scan the card when a bin or pail runs low

Every stocked item gets a durable card with a QR code, from a pail of purge compound to a box of desiccant to a pallet of gaylords. A process technician scans it with any phone, no extra hardware, no login friction.

2

The order fires automatically

The scan hits Arda's backend, which places the reorder at the right quantity from the right supplier. No purchase order to type.

3

See every card, pulled to restocked

Purchasing and the owner watch which cards are pulled, on order, or restocked across parts and locations, without walking the floor.

Each card encodes a proven loop sized to your real consumption: reorder point, the two-bin system, min/max levels, and safety stock. The math lives on the card, not in someone's head.

Built for the press floor, not the back office

Count-everything tools fail because they add a task. Arda removes one. That is what holds compliance past week one.

No counting, ever

The card is the replenishment signal, on every item you stock. Nobody tallies stock or runs a cycle count to make the numbers real.

Adoption that holds

The simplest way to do the job is to scan the card, so compliance sticks in the middle of a changeover, where a data-entry screen never wins against press time.

One scan, any phone

No scanner gun, no new login, no training day. A process technician scans with the phone already in their pocket, so nothing new stands between them and the reorder.

The signal lives on the floor

Reorder point, min/max, and safety stock are baked into the card at the point of use, not buried in a back-office sheet that drifts the moment demand shifts.

What each role gets

Process technician / setup

One scan when a pail or bin runs low, and the refill is already moving. Same motion at every press. Nothing new to learn.

  • No hunting for whoever does the ordering in the middle of a changeover. Scan the empty pail and get back to the press.
  • No changeover that stalls because the purge is gone and the last pail left the shelf without a word.
  • Nothing new to learn. If you can scan a card, you already know the whole system.

Buyer / materials planner

Your MRP run keeps doing resin, color and inserts. The shelf it never covered reorders itself at the right quantity, with no stack of manual POs behind it.

  • No rush freight on a heater band because the spare left the shelf three weeks ago and nothing said so.
  • No walking the floor before every order to ask what the presses went through.
  • Pulled, on order, restocked: every card's status in one view, so nothing inbound is a mystery.

Plant manager / owner

Press time stops leaking into shortages nobody planned for, and the second shelf finally produces real consumption data instead of guesses.

  • Changeovers finish on schedule, because the purge, the release spray and the wear parts are where they are supposed to be.
  • Real consumption on the off-BOM shelf, so the next quote carries a number instead of a feeling.
  • One loop across every press and every shift, priced per card with unlimited users.

Frequently asked questions

Does Arda replace my plastics ERP?
No, and it should not. If you run IQMS/DELMIAworks, CyFrame, Plex or Epicor, you chose it on purpose and it is doing the job it was built for: MRP against your release schedule, resin and masterbatch planned to the part number, press scheduling, job costing, quoting and lot genealogy. Arda does not go near any of that. It runs the physical replenishment loop on the shelf beside the press, on the items that never made it onto a bill of materials. Cards go on purge compound, mold release, desiccant, heater bands and gaylords first, and you can extend the same loop to on-BOM items later if you want one motion everywhere. It integrates with QuickBooks, NetSuite, Odoo, Xero, Shopify, Stripe, Airtable, Make and Zapier, plus a REST API, so there is no rip and replace.
My resin and masterbatch are already on the BOM. What is left for Arda to do?
Everything the BOM has no line for. A bill of materials describes a part, so it can only ever cover what goes into the part. Purge compound belongs to a changeover, not a part number. Desiccant belongs to a dryer. Heater bands belong to a press. Gaylords belong to a shipment. None of those get planned by anything, and any one of them stops the press just as hard as a resin shortage. Put a card on each, and the reorder fires when someone pulls the last one.
What is the fastest way to stop running out of purging compound?
Make the reorder physical instead of scheduled. Purge consumption follows your changeover calendar rather than your part volumes, which is why a forecast never gets it right. With Arda, the pail carries a card sized to your supplier's lead time and your changeover rate. When a tech takes the last one from the buffer, they scan the card and the order is already moving before the next color change is even scheduled. Nobody has to notice the shelf, and nobody has to remember to ask.
How do I set up kanban for a molding plant that runs three shifts?
Put the card at the point of use rather than in the stockroom, so whoever empties the bin is the one who scans it. Size each card to lead time times consumption plus a cushion, and let the buffer cover the wait. Because the card is physical and the scan takes a second, second and third shift trigger the same reorder first shift would have, with no handover note and nobody waiting for the buyer to come in. Arda is priced per card with unlimited users, so every shift can scan without adding cost. More on the two-bin system.
What does Arda cost for a molding plant, and is there a free trial?
Arda prices by card, not by seat, so users are unlimited on every plan. Free is $0 a month for up to 10 cards, which is enough to card purge compound, desiccant, mold release and your top wear parts and see the loop run. Growth is $250 a month billed annually, or $291 month to month, and covers 250 cards at $1 a card. Pro is $500 a month billed annually for 500 cards, plus AI-tuned kanban quantities and multi-card loops. Enterprise is custom. Paid plans include a 7-day free trial, and annual plans add 2 free months and a $650 welcome kit after an onboarding call. Start on one press and expand across the plant when it has proven itself.
