Comprendi rapidamente la causa anomala dei fustellatura

I. Specifiche scadenti (dimensioni richieste dalla fustellatura dei disegni di base)

1. La specifica della matrice punzone / coltello è errata: (la dimensione del disegno non soddisfa i requisiti / la matrice non è realizzata secondo il disegno);

Contromisura: rifare il disegno o riaprire lo stampo.

2. Le specifiche teoriche non corrispondono all'uso effettivo: (la dimensione teorica del prodotto non corrisponde all'assemblaggio fisico, con il risultato che l'effetto o la funzione dell'assemblaggio non possono essere raggiunti);

Countermeasure: Remake the specifications and technical data according to the actual distribution effect, and change the product processing mold and confirm the actual distribution of the product.

3. Deformation caused by mold wear or damage: (Insufficient mold maintenance or improper use, resulting in excessive use of the mold or excessive wear)

Countermeasure: Regularly inspect the mold, confirm the mold life and maintenance methods, and regularly maintain and remake the mold.

II. Poor registration offset (big and small sides, or no at all)

1. When the material is cut or the paper is slit, the cutting edges are not uniform. If the subsequent positioning is based on the cutting edges, the hidden danger of die cutting will occur. Especially refers to paper release paper products.

Countermeasure: When stipulating the slitting or slitting, the material or release paper "S" edge difference requirements can be quantified and measurable; the storage conditions after the slitting of the rubber must be implemented in accordance with the regulations to prevent the relative displacement of the rubber material and the roll, which affects complex.

2. For the first composite of PET base paper products, the slitting edge or slitting edge is used as the positioning; when the first die cutting, it is usually punched and positioned, and when the second die cutting is used, the positioning is the first. Hole tracking formation. At this time, if the tracking hole during the third die cutting is punched again, the tracking hole twice will be relatively offset, which will affect the size of the final molded product.

Countermeasure: When punching the positioning hole in the second die cutting after die cutting, the speed of the first die cutting, the speed of the second compound and the relative position of the two materials are the key factors affecting the second die cutting. The positioning adjustment during the second die-cutting, in addition to the automatic chase of the machine, must also ensure the adjustment of the jump distance. The positioning hole is pressed in the direction of the paper ejection, and the front of the positioning hole is pressed, which means that the jump distance is not enough or the paper feed speed is slow; the positioning hole is pressed in the paper output direction, which means that the jump distance is too large or the paper feed speed is too fast.

3. There is a high probability that the products that have been compounded and die-cut many times will have large and small edges, so every time you compound and die-cut, you need to pay special attention to the material head and the tail; the difference.

III. multiple materials, colloidal residual silk, release paper or product burrs

1. The blade of the punch / knife die is worn or deformed, and the defect is the main reason.

Countermeasure: Regularly check and maintain the punching die, sharpness, deformation, or defect of the knife. Time, personnel, and maintenance methods need to be documented.

2, release paper or product burrs, except for material reasons, not enough punching or insufficient pad cutter, incorrect waste disposal methods are also the reasons.

Contromisura: è la chiave per testare e confermare l'effetto di punzonatura del primo stampo o del primo stampo 10-15. In generale, può essere trovato e regolato se la perforazione non è in posizione e il pad non è sufficiente. Il metodo di scarico dei rifiuti è sbagliato. Vengono contati i risultati della bava di scarto della produzione di massa. Confrontando altri metodi di scarico dei rifiuti, puoi ottenere una soluzione.

IV.Difetti come bolle, impurità e bordi della protettiva che appaiono sulla superficie del prodotto fustellato

Tutti sono causati da protezione impropria, mantenimento della pulizia ambientale, spremitura errata del prodotto; attrito eccessivo tra i prodotti; tutte sono le ragioni. La pulizia e la protezione dei sigilli del prodotto in officina e durante il trasporto richiedono pratiche e formazione documentate e operative.
