Can we order small quantities to test a product in a few stores?
Yes. There is no minimum order quantity, so a first run can be sized for a test and the same tool used for the full rollout.
Industry
Injection Molding for Lawn and Garden
Garden products are sold in a few busy months, then left in a shed, a truck bed, or out in the sun. The plastic has to survive the neglect as well as the work.
The season
Built for spring, stored all winter
The calendar shapes the program as much as the product does.
Retail buyers commit to garden products months before the first warm weekend, and reorders come fast if a product sells. That means tools have to be finished and approved well before the season, and the same tool has to restart cleanly after sitting idle for most of the year.
The products lead hard lives. A string trimmer housing gets dropped on concrete, splashed with fuel, and packed with grass clippings. A hose nozzle freezes with water inside it. A spreader hopper sits in the sun full of fertilizer. The resin list follows from those, not from the drawing.
Product by product
What each garden product does to its plastic
Different products, different enemies.
| Product | What wears it out | Usual resin |
|---|---|---|
| Trimmer, blower, and mower housings | Drops, engine heat, fuel splash, vibration | Glass filled nylon |
| Battery tool and charger shells | Drops and a clean look on the store shelf | PC/ABS or nylon with a TPE grip |
| Hose nozzles and connectors | Freezing with water inside, being stepped on, sun | Glass filled nylon or acetal internals, TPE overmold |
| Sprinkler heads and gear drives | Grit in the water, constant rotation, sun | Acetal gears, UV stabilized housings |
| Spreader hoppers and sprayer tanks | Fertilizer, herbicides, and years of sun | UV stabilized polypropylene or HDPE |
Watering
Watering parts that survive a freeze
Water left in a nozzle or valve over winter expands as it freezes and pushes the plastic outward.
- Tougher resins that stretch before they crack hold up better than stiff, brittle ones when ice forms inside
- Internal shapes that drain when the product is hung up leave less water to freeze
- Threads that connect to a metal spigot often get a metal insert or a thicker collar to take the wrench
- A soft TPE grip overmolded on the body protects the part when it is dropped and feels better in wet hands
FAQ
Questions from lawn and garden brands
Can one tool run a product in different brand colors?
Yes. Color is changed at the press, so one housing can ship in several colors for different retailers or private labels.
Which resin handles fuel splash on a trimmer housing?
Glass filled nylon is the common choice. It resists gasoline and oil, stays stiff near a hot engine, and survives drops.
Who owns the tool if we change suppliers?
You do. The customer owns the tool once the tooling charge is paid, and can request it at any time.
