Hoppers ASA in 6 mm for Hydroponics And Greenhouse – Formed to Drawing

These ASA hoppers are thick gauge vacuum formed parts supplied to drawing for hydroponics and greenhouse. They are formed from ASA sheet at 6 mm, trimmed on 5-axis routers and inspected against the drawing before packing. Buyers choose this route where a metal fabrication is too heavy, or where injection moulding tooling cannot be justified for the volume.

Product specification

Key features

• One piece shell replaces a fabrication, so assembly hours drop
• ASA keeps the weight down while stiffness is held through the formed shape
• Uv stabilised as formed finish as standard, further finishes on request
• Trimmed on 5-axis routers, so mounting holes and cut outs match the drawing
• Tooling stored against the part number for repeat and spare orders
• RoHS compliant grades available

Typical applications

• grow trays
• reservoir liners
• seedling trays
• channel covers
• hoppers used across general hydroponics and greenhouse builds

How it is made

1. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
2. The part cools on a jig so the shape is held while the material stabilises.
3. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
4. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. Sheet is dried when the material needs it, then heated to forming temperature on the machine.

Material: ASA

ASA keeps its colour and surface under UV better than ABS, which suits outdoor covers that are not painted.

Design notes

• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• use corner radii of at least three times the sheet thickness to avoid thinning
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time

Finishing and assembly options

• UV stabilised as formed
• two coat polyurethane paint
• EMI shielding coating
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• PPAP or ISIR on request
• REACH compliant sheet available
• ISO 9001 quality system

Packing and delivery

Parts are nested to save freight, with returnable dunnage available on repeat routes. Standard lead time to first article is 7–15 working days, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

Are spare parts available later?

Tooling is stored against the part number for the life of the programme, so replacements or spare panels can be released at any time.

Can you make it in another material?

Any grade in this family can be swapped in. Send the requirement and the material will be quoted with the price difference shown.

How fast is the first article?

Seven to fifteen working days from drawing release for sample tooling, with production tooling in three to four weeks.
