Predictika · Injection molding machine configuration and mold fit

An AI sales agent's injection molding machine order, checked before it goes out

An AI sales agent prepares an order for an ALLROUNDER 270 S injection molding machine: clamping force, injection unit, screw and drive, for a customer's mold and material. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the machine's published technical data and returns a verdict, every reason and the figures it computed.

Scope: ALLROUNDER 270 S hydraulic injection molding machines: clamping force, injection unit, screw, drive, mold fit and shot weight by material. See everything this validator covers

This validator models the ALLROUNDER 270 S, not just the scenarios shown below.

  • Machine type — clamping forces of 250, 350 and 400 kN; injection units 70, 100 and 170; the 250 kN machine takes injection unit 70 or 100; one or two pumps on 250 and 350 kN, two pumps or an accumulator on 400 kN.
  • Screws and shot weight — each injection unit takes three screw diameters (unit 70: 18, 22, 25 mm; unit 100: 20, 25, 30 mm; unit 170: 25, 30, 35 mm); each combination has a maximum injection pressure and a maximum shot weight for ten materials (PS, ABS/SAN, PMMA, PC, PA 6.6, POM, PET, PE-HD, PP, PVC-U). The quote's stated shot weight is compared with the one the screw gives.
  • Mold fit — clamping force needed against the machine, opening stroke up to 350 mm, mold up to 380 x 380 mm, mold height of at least 200 mm, mold height plus stroke within 550 mm of platen daylight, and a movable mold half of up to 135 kg (up to 200 kg only with alternative equipment, which needs a person to confirm).

Any ALLROUNDER 270 S order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (ARBURG does not publish list prices, so this validator produces no price build-up or line-item quote), the 270 S COMPACT and other ALLROUNDER sizes, electric, hybrid and vertical machines, options such as robots or hot runners, and cycle-time or injection-flow figures.

The AI sales agentBuilds the machine order from the conversation and says it is ready.
Predictika validatorChecks every rule at once and returns the verdict, each finding, and the computed figures.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Injection units and screws that pair up differently on each unitOnly with care
Each injection unit has its own screw diameters, pressures and shot weights; a product rule per pairing works, but every new screw or unit is another set of rules to maintain.		Unit and screw are in one request and the pairing, pressure limit and shot capacity are looked up together on every call.
Drive options that depend on the clamping forceOnly with care
A rule per clamping force and drive. It works, but the same facts are repeated across rules.		Clamping force, injection unit and drive travel in one request and every combination is checked together.
Mold fit: size, height plus stroke against daylight, weightOnly with workarounds
The daylight check adds two fields on different lines and compares the total with a limit, and the weight has a hard limit and a softer one that needs a person; each is its own cross-line rule.		Every mold figure is in one request, so the sums and limits are checked together, whichever order the choices arrive in.
Shot weight that depends on the material and the screwOnly with workarounds
A lookup of nine screw combinations by ten materials, which is usually a custom table or a long list of rules.		The material and screw are looked up together and compared with the shot the part needs.
Stated shot weight that must match the machineOnly with care
A stated figure is a free-entry field; a rule can compare it with a computed one, but someone has to write and maintain that comparison.		The stated figure travels with the order and is compared with the computed figure on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for an ALLROUNDER 270 S injection molding machine: clamping force, injection unit, screw and drive, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the machine's published technical data and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote an ALLROUNDER 270 S. The mold is 340 x 340 mm and 280 mm high, its movable half weighs 120 kg, and it needs 300 kN of clamping force and a 250 mm opening stroke. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The 400 kN machine is offered only with two pumps or an accumulator, not with one pump. The process needs 1,800 bar of injection pressure; the 30 mm screw on injection unit 100 reaches at most 1,390 bar. The part needs a 55 g shot, but the 30 mm screw on injection unit 100 holds at most 51 g of this material.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for shot weight that depends on the material and the screw, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the drive to two pumps.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with two findings, all in one answer. The process needs 1,800 bar of injection pressure; the 30 mm screw on injection unit 100 reaches at most 1,390 bar. The part needs a 55 g shot, but the 30 mm screw on injection unit 100 holds at most 51 g of this material.
    12. 
      
  12. One finding cleared. Still blocking: injection pressure above the screw limit and shot weight above the screw capacity.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the injection unit to 170 EUROMAP size and the stated maximum shot weight to 77 g PS.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. Both earlier findings are cleared, and the validator's figure matches the quote.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    19.
