I have no drawing — can you still make the part?

Yes. Send clear photographs of the old part with a scale reference, plus the machine brand and model from the nameplate. If you can measure anything at all, the screw diameter or barrel length is the most useful figure you have. Where a part is critical to fit, we would rather you sent the old piece back to us to measure.

Plasticizing parts made to order — screws and hoppers included

Send a drawing, photos of the old part, or just your machine model. We make it to size — material and quantity are flexible.

One piece or a batch Made to drawing or sample Fits and holds up in daily use

What we do

Replacement parts for injection molding machines

We make parts for injection molding machines — whether you need one replacement or a batch, we can do it. There are many brands and models out there, and original parts can be hard to source or take weeks to arrive. Send us the drawing or the old part, and we will match it. The goal is simple: it fits, and it holds up in daily use. If your part is not listed, just send a photo — we will tell you whether we can make it and how, before any work starts.

Common materials, chosen to match your job

Final choice depends on actual working conditions

We work with all the commonly used plastics, and can run your specified grade. Not sure which one you need? Tell us where the part sits, what load it carries and what material it touches — we will help you pick.

Material	What it is good for	Typical parts
PP (Polypropylene)	Light, tough, good all-round chemical resistance	General structural parts, hoppers
PE (Polyethylene)	Flexible, good at low temperature, acid/alkali resistant	Bins, protective covers
ABS	Rigid, easy to mold and finish	Housings, covers
PET / PBT	Wear-resistant, dimensionally stable, good insulation	Structural and fixing parts
POM (Acetal)	Hard, wear-resistant, self-lubricating, accurate	Gears, bushes, moving parts
PA (Nylon)	Tough and wear-resistant; can be glass-filled	Loaded parts, drive parts
PC (Polycarbonate)	High impact resistance, transparent	Guards, sight windows
PC / ABS	Good balance of toughness and surface finish	Machine housings
PMMA (Acrylic)	Good optical clarity	Windows, transparent covers

Reinforced / compounded grades: glass-filled, flame-retardant, conductive, UV-stable. · Special requirements: need to match an imported grade, a named supplier, or food-contact / environmental requirements? Mention it up front and we will source the material accordingly.

Chinese-built machines we cover

What matters is the drawing, the old part and the machine model

These are the brands we make parts for most often. If yours is not on the list, most Chinese machines can still be handled — what matters is getting the drawing, the old part and the machine model right.

How an order works

Price and lead time agreed before production — nothing gets added halfway

Send the details

A drawing is best. No drawing? Send photos of the old part and a clear photo of the machine nameplate with the model.

Confirm requirements

Material, quantity, tolerances and surface finish — agreed before we quote.

Quote & lead time

Unit price, lead time and shipping method are settled up front; nothing starts until you are happy with it.

Produce & ship

Large items go by freight, small items by courier, and the tracking number comes to you.

Our commitments

One-off parts and batches are both welcome. In a hurry? Tell us and we will move the job up the queue. New to working with us? Start with one or two sample pieces, and plan long-term once they work out. If a part does not fit or the dimensions are off, contact us promptly — we will see it put right.

Questions about custom parts

Including first-time orders and one-piece quantities

Yes. Send clear photographs of the old part with a scale reference, plus the machine brand and model from the nameplate. If you can measure anything at all, the screw diameter or the barrel length is the most useful figure you have. From that we can normally produce the part to the dimensions the machine was built for. Where a part is critical to fit, we would rather you sent the old piece back to us to measure.

One piece. We are set up for single replacement parts as well as batches, because most customers test with one or two pieces before committing to a full set. If your part works, place the remainder — and if it does not, you have not bought a batch of unusable parts.

Tell us where the part sits, what load it carries and what it touches. PP and PE for general hoppers and covers, ABS or PC/ABS for housings, POM for gears and moving parts where dimensional accuracy matters, PA for loaded parts, PC or PMMA where it must be transparent. If you need it to match a specific imported grade or a food-contact requirement, say so up front and we source accordingly.

Large items by freight, small items by courier. The lead time is stated in the quotation before any work starts, and depends mainly on size and whether reinforced grades are involved. Typical range is well within a couple of weeks for standard items.

Contact us straight away, and we will put it right at our cost. Dimensional accuracy is checked before shipping rather than sampled from, so a mismatch should not happen — but if it does, that is our error to fix, not yours to absorb. Send a photograph and the machine model and we will work out what went wrong.
