POROSITY ANALYSIS WITH INDUSTRIAL CT

GET THE INSPECTION CAPACITY YOU NEED – Anywhere. Any­ti­me. Fast.

Identify pores, blowholes & inclusions

If pores, blow­ho­les & inclu­si­ons get out of hand, com­pon­ents can­not meet the necessa­ry requi­re­ments. Mini­mi­sing the­se defects is par­ti­cu­lar­ly dif­fi­cult when star­ting a new pro­duc­tion. Con­ven­tio­nal die cas­ting, for examp­le, can hard­ly be pro­du­ced free of poro­si­ty. For this rea­son, a poro­si­ty ana­ly­sis is usual­ly necessa­ry to opti­mi­se pro­ces­ses & qua­li­ty control.

Micro­vis­ta sup­ports you here by inspec­ting small & lar­ge quan­ti­ties for signi­fi­cant imper­fec­tions in a fast & auto­ma­ted CT scan pro­cess. Alter­na­tively, high-reso­lu­ti­on & stan­dard-com­pli­ant CT scans with a detail­ed ana­ly­sis by our experts can sup­port your sam­pling. You will recei­ve a high level of pro­cess relia­bi­li­ty & indi­vi­du­al eva­lua­tions at any time.

Serial testing

Quick inspection of fault focal points

In the deve­lo­p­ment pha­se of a new com­po­nent or when new fault points occur, you want to know quick­ly whe­re you stand. This saves money and ner­ves. The digi­ti­sa­ti­on of light metal or plastic com­pon­ents with an enve­lo­ping cylin­der of d= 500mm & a cumu­la­ti­ve mate­ri­al coverage of approx. 200 mm can be done in a few seconds. 
The high scan­ning speed enab­les favoura­ble inspec­tion cos­ts (here to the pri­ce list) & crea­tes an eco­no­mic alter­na­ti­ve to scrapping.

Typical field of application

Example: Automated porosity analysis

Sealing lips are exami­ned in an auto­ma­tic pro­cess. The colour-coded test zones allow for dif­fe­rent pore sizes in each case.

In order to bet­ter check for imper­mis­si­ble pores, the test zone is unrol­led automatically.

Short­ly after the CT is unloa­ded, it is alrea­dy clear whe­ther the inspec­ted com­po­nent belongs to the OK or NOK cate­go­ry. This means that the appro­pria­te sor­ting can also be car­ri­ed out in the same work step.

Procedure of a serial testing

Shipping the components to Microvista

Do you want to out­sour­ce your ent­i­re qua­li­ty con­trol? For lar­ger quan­ti­ties, Micro­vis­ta acce­le­ra­tes pro­ces­ses through automation.

Evaluation in the cloud

Do you have your own CT? Then upload your scans to our cloud and have them eva­lua­ted auto­ma­ti­cal­ly. This saves you an enor­mous amount of time, as a manu­al eva­lua­ti­on is not required.

Mobile CT solution

You only need a CT inspec­tion tem­pora­ri­ly & do not want to ship your com­pon­ents for an inspec­tion? Then rent a CT sys­tem only for as long as you need it! With Microvista’s uni­que mobi­le CT solu­ti­on you save high invest­ment cos­ts & long wai­t­ing times.

Individual part testing

Detailed sampling of a few components

Sam­pling accord­ing to the various stan­dards of car manu­fac­tu­rers and asso­cia­ti­ons requi­res a high-reso­lu­ti­on scan data set. The exe­cu­ti­on is pro­cess-safe, stan­dard-com­pli­ant and in a prac­ti­cal form of pre­sen­ta­ti­on. Reli­able state­ments with con­cre­te indi­ca­ti­on of remai­ning uncer­tain­ties are a mat­ter of course.

A high reso­lu­ti­on enab­les detail­ed state­ments to be made on the con­cre­te cha­rac­te­ris­tics of the blow­ho­le or pore geometry.

Sampling procedure

Execution according to P202 or manufacturer’s standard (ZFN 1136, VW 50093)

In addi­ti­on to the sup­port pro­vi­ded by indus­try-stan­dard tools, Micro­vis­ta also works with in-house resour­ces to pro­du­ce stan­dard-com­pli­ant test reports.

In the stan­dard pro­cess, all orders are pro­ces­sed wit­hin 14 days at the latest.

If the parts do not have a seri­al num­ber, they are regis­tered with an inter­nal num­ber when they are recei­ved. Both the scan data and the ana­ly­ses & reports crea­ted in sub­se­quent pro­ces­sing steps then refer to this num­ber. This ensu­res 100% tracea­bi­li­ty of all work steps.

Reli­able ana­ly­sis results do not come about on their own, even with the best equip­ment. In addi­ti­on to the exper­ti­se of the pro­ces­sing staff, estab­lis­hed pro­ces­ses for uncer­tain­ty eva­lua­ti­on are required.
