Considerações comuns sobre o design do molde da grade
Gating & weld lines
- Mantenha as linhas de solda longe das áreas de emblema e das nervuras de alta visibilidade
- Fluxo de equilíbrio para evitar chutes curtos em padrões de treliça fina
- Cold-slug and filter strategy to protect cosmetic surfaces
Warpage & flatness
- Parede uniforme com nervuras controladas para reduzir o afundamento e a torção
- Simetria de resfriamento para evitar a elevação dos cantos
- Process-window guidance for packing, melt and mould temperature
Ventilação
- Micro-vents at end-of-fill and trapped-gas pockets
- Prevent burn marks on glossy and textured surfaces
- Serviceable vent locations for long production runs
Ejection & handling
- Ejector layout that protects thin ribs and clips
- Evite marcas de testemunhas em superfícies de exposição
- Handling and packing advice for deformation control
Automotive grille moulds — FAQ
Que tipos de grade vocês suportam?
Center grilles, grille frames, emblem bases, air-intake trims and related front-end decorative parts for passenger cars and SUVs. Send your CAD and appearance class and we confirm the split, gating and texture plan.
What is the typical lead time for a custom grille mould?
It depends on size and surface requirement. A practical range is 45–75 days including DFM, machining, assembly and T0 trials. With a fixed SOP date we can propose a fast-track plan.
Quais aços e acabamentos de superfície você recomenda?
Steel and polishing or texture follow the surface class, resin (including fillers) and shot-life target. For high-cosmetic areas we plan the finishing early to cut rework after trials.
Como você controla o empenamento em estruturas de grades grandes?
By balancing cooling, optimising rib ratios, using stable gating and setting a proper process window during trials. Fixture or packing methods are recommended where post-mould deformation is a risk.
Vocês fornecem relatórios de amostragem?
Yes. Trial deliverables can include key dimensions, photos and video, defect notes (sink, weld lines, burn marks, flash) and corrective actions for the next stage.
Request a grille mould quote
Send your CAD/2D drawings, resin, surface requirement and target annual volume. You get DFM notes, a tooling concept and a quotation plan back.
