P:

How is molded grating different from pultruded grating?

A :

Molded grating is made by pouring resin over fiberglass mats in a mold, resulting in a bidirectional strength pattern. Pultruded grating is made by pulling continuous fiberglass strands through a resin bath and a heated die, offering higher longitudinal strength.

P:

What type of press is used in molded grille production?

A :

A hydraulic compression press with heated platens is most commonly used. Press capacity ranges from 500 to 1500 tons, depending on the grille size and thickness.

P:

What materials can the machinery handle?

A :

The machinery is compatible with: Fiberglass (E-glass or S-glass) Resins (polyester, vinyl ester, epoxy, phenolic) Additives like UV inhibitors, pigments, and flame retardants

P:

How are molds designed for different grille sizes?

A :

Molds are custom-fabricated based on required: Mesh patterns (square, rectangular) Panel thickness (e.g., 25 mm, 38 mm, 50 mm) Grille surface type (concave, gritted, plain)

P:

What’s the typical cycle time for one molded grille panel?

A :

The complete cycle—from lay-up to demolding—usually takes 30–90 minutes, depending on panel size, resin type, and curing system.
